The other big feature of MythTV .22 is support for hardware acceleration on certain NVidia cards. I looked up VDPAU and selected the least expensive card that supported all of the features. I found a great deal on a  PNY VCG8600GXXB GeForce 8600 GT on NewEgg for a mere $25 after MIR.

When everything arrived, I set aside a full day for the upgrade. I moved the whole MythBuntu install onto a USB flash disk using Unetbootin, backed up the old database and the etc folder, disconnected the old HD and installed the new HD. Booting from the flash disk worked fine and I was quickly into the setup. Installation was a snap and recognized all of the hardware immediately, a task that has taken many weeks before. I followed the steps from MythPVR.com to migrate existing recordings to a new server. There is a comment at the end of the article that if the database is different enough, you should add a -f option to the import which did the trick for me.

I pointed the storage groups for videos at my already installed media drive (640GB) and then hot plugged in the old 500GB HD (love SATA), mounted it and then copied the recordings to the new recordings path. I launched the frontend and recordings were up and running. I was a little bummed that the video metadata didn’t come through but instead of going back to the original database, I used the included jamu script to gather metadata for all of my movies. It looked a lot nicer and the information was much more accurate and detailed than before.

I went into the Playback settings and set it for VDPAU+. The difference is amazing between the old video card and this one. It’s not just the VDPAU but having a dedicated card that seems to make the difference. The one major problem I did run into was pixelation of anything that was in MPEG2 format (recordings). I finally tracked down a thread that this is a known bug on certain motherboards and they are working on a fix. In the mean-time I have reverted to CPU Slim.

Overall I am very pleased with the new software and distribution.

Once the DVD’s are copied into their individual episodes, it’s time to hit them with AutoGK. AutoGK is a simplified version of GordianKnot, a very feature rich utility for conversion. AutoGK dumbs down and simplifies the interface and works great for doing this. Follow step 4 in the in-depth guide above to use AutoGK for the final conversion from DVD VOB/IFO to an AVI. I selected 350MB for my final file size of a 45 minute episode.

Now that you have all of your episodes in avi format, it’s time to move them onto your Myth box and into the menu system. I created a directory structure under the main Myth Videos directory of Series Name\Season X\Series Name S0XE01.avi.

I modified a script by Steve Adeff called ragetvgrab-0.5.pl. The original script was supposed to insert video files and their meta-data into the recording table so that series would show up in the recording table. I didn’t have a lot of luck and preferred for these to show up in the MythVideo section. Here it is RageTVGrab Script (Video Metadata Edition). Basically you can just run it with the full path to your avi/video file:

./ragetvgrab-videos-0.1.pl -F /storage/videos/Voyager/Season\ 5/Star\ Trek\ Voyager\ S05E25.avi

This will prompt you with the meta-data collected from the ragetv site to verify accuracy. Hope this works as well for you as it does for me.

If you want to do an entire directory at once, you can use some bash magic:

IFS=$'\n' # If your files have spaces or odd characters in the name, set this first
for file in `ls -1 /storage/videos/Voyager/Season\ 7/`; do /root/ragetvgrab-videos-0.1.pl -i -F /storage/videos/Voyager/Season\ 7/$file; done

Setting IFS will keep the for from splitting on the spaces. Make sure the paths are correct.

If you end up with odd chars in the title, you can clear them out with a little mysql. Go into mysql and run the following command:

 UPDATE videometadata set `plot` = replace(plot, "’", "'")

How about that “change layout” junk that they are adding now, easily fixed

UPDATE videometadata set `title` = replace(title, ' (<a href='/mytvrage.php?page=my_layout'>Change Layout</a>) ', '') 

I have been a die hard TiVo fan from the start. I won my first TiVo in an essay contest with an essay on why every pregnant woman needs a TiVo. The TiVo was great to begin with, it was provider agnostic, Linux based, configurable, upgradable and with a few additional codes you could enable some of the anti-commercial features like 30-seconds skip. When I switched over to DirectTV and purchased a DirectTivo, I noticed that each version of the software that came out provided less and less end-user features and more provider features. It is the sad fate of most companies that they must first service their stock holders and then their retail customers. I wanted to get into a series 2 TiVo but then DirectTV decided they could do it better and abandoned the TiVo platform altogether. I was also looking in to HD and I realized I could either use money or brains to solve the problem. It was time to take control of my PVR and try to provide TV recording, on-demand viewing of my DVD collection and some integrated web services like weather and browsing.

My first attempt at a PC based PVR was Microsoft Windows Media Center. I’ll admit that it was easy to setup, quick to configure and worked very well. However I felt the DRM noose from the get-go and realized that it was going to be incompatible with my long term goals. After building a new primary box, I rebuild my AMD Athlon 64 3200 into a box running Fedora 7.

I followed Jared’s Fedora MythTV howto and began creating my first MythTV system. After a few days of playing with it on and off, I had it running. I quickly recognized that I would need to add some hardware to get the system going so I went out to CompUSA and bought a Hauppauge WinTV-PVR-150 MCE capture card. This solved both the capture problem and the remote control. After all, who wants a PVR that only plays DVD’s and that you have to control with a full keyboard. I had toyed with the remote control that came with my Dell XPS M170 but it turns out that even though it looks like an MCE remote, it isn’t and won’t work with lirc at all. The next step was moving it into a case that looked at home in my entertainment center. I picked up a Silverstone LC10 and moved the system into it’s new home. I was still using an old Toshiba 32-in CRT TV that I’ve had for about 10+ years and it was starting to develop some purple and green spots in the corners of the screen.

Before I got into replacing the TV, I wanted a tested solution in place that was storing HD content. After researching options for HD capture, I settled on a relatively new solution from Silicon Dust called the HDHomerun. This miracle device provided 2-tuner HD support in an external appliance that hooked directly to the network via Ethernet. No internal installation meant better compatibility and no need for drivers. During this trial I had purchased a picture frame antenna from Radio Shack that was feeding my 150MCE for over-the-air TV channels. It worked pretty well and I was able to pull in a good signal for the local channels. I had the MythTV system and my DirectTiVo running side by side recording the same shows so that in case the MythTV system had a problem, I could easily watch the show on the TiVo. This also helped to gradually introduce the MythTV to the family and help them get used to it. All I had to do was copy a few of the kids favorite DVD’s into Myth Videos and they were on-board. My wife really enjoyed the automatic commercial skipping and while still hesitant to the change, was warming to the idea day by day.

Switching over from the 150MCE to the HDHomerun was fairly painless, the signal quality jumped way up with a digital solution and provided a comparable signal to the DirectTiVo. I moved the antenna and the HDHR down to the walkout basement and quickly realized that it might be a good idea to get a better antenna. While some channels were reasonably strong, others were unreceivable. I once again researched and picked up a $50 DB2 antenna from Antenna’s Direct. Using a compass and antennaweb.org, I mounted it to the ceiling in our unfinished basement and aimed it. The signal difference was night and day. It was about this time that I made another commitment to the MythTV system by purchasing guide data from SchedulesDirect, the pay service for guide data for MythTV. There was a lot of concern when Zap2It, the previous free provider decided to bow out of their deal to provide schedule data but the MythTV group came through with a great solution. For several weeks we enjoyed all of our favorite shows in digital broadcast and could see the quality difference in the HD signal but couldn’t really take advantage of it with the old TV. We were switching to the DirectTiVo less and less. I had a coax line run from the back of the DirectTiVo to our bedroom and we were still using it for before-bed shows but it was being phased out. I was still having some problems with the ATI Radeon X850 card so I took the opportunity to pick-up a card with better Linux support, an Asus NVIDIA 6200 which had good reviews on the MythTV-Users mailing list (speaking of which, you can see my sordid posting history there to see some of the struggles and solutions). Having the NVIDIA card in there made all the difference. Everything looked very crisp and clean and I verified with a few downloaded examples that the system was capable of HD.

My failing TV, having a DVR that was capable of HD and the support of my wife led me to getting a Samsung LNT4665F 46-in 1080p HD TV (a fathers-day gift dream). I also bought an HDMI to DVI cable and hooked the MythTV system to the new HDTV. I changed the resolution of XWindows to 1920×1080 and marveled at what I had put together. I watched a few of the local newscasts in awe of the image quality. As we were watching Law and Order in HD one evening, my wife asked me why we were still paying for DirectTV. I told her that we still needed it for the bedroom TV and she said it would be OK to cut that off. We had a few dozen of our favorite shows on the DirectTiVo so I called them up the next day and cancelled my service. It was sort of a liberating feeling. We were still getting all of our favorite shows and not paying a dime for them in recurring costs. I had a few shows that I was missing but it was easy enough to find them available as bittorrents and transferring them to the MythTV system was a breeze. I also ran into a little gem called TED that would automatically monitor the bit torrent sites for new episodes and download them. I transferred a good deal of my DVD’s to the system as well. Things were going well except that we were running low on shows in the bedroom.

I built another system from NewEgg specifically for upstairs this time with a 250GB HD and a motherboard with an on board NVIDIA card. The hardest part to setting up this system was running an Ethernet connection to the bedroom. I didn’t have to worry about any capture cards so it was pretty straight forward. I also decided on a smaller case since I could build on a micro-atx form factor. The NMEDIAPC 200BA fit the bill although it didn’t take me long before I realized the LCD display was nothing more than a fancy fan-speed/temperature monitoring device, not a true LCD display for MythTV. The good news is that NMEDIA has a list of good LCD’s that are controllable and fit in the box. Another good idea in concept is that you can add a disassembled MCE IR receiver inside the box. They created an internal mounting bracket and supply the cable to connect it to the USB header on the motherboard. In practice though there seems to be a reflection problem or the window isn’t wide enough because I have a hard time getting any remote to be received without multiple repeats of the same command, even with the repeat set to 5 in lirc.conf. We are able to watch all of our recorded shows in the bedroom again. I was a little frustrated when I found out that MythVideo isn’t shared quite as easily. I ended up copying my Star Trek: Voyager Series DVD’s onto the upstairs MythTV system using DVD Decrypter and AutoGK. I read that you can create NFS shares between the two MythTV systems and then you can see videos from both drives but I have yet to tackle that challenge. The down side is now every time I go to manage video’s, it wants to remove links to the videos stored on the other side. Not a big deal but I am doing a lot more database management through phpmyadmin.

I am very happy that I have taken control of my media needs. I am using MythTV for what it is designed for and not taking advantage of much else yet. I am getting consistently high quality recordings of all of my favorite shows too and can share the recordings to my bedroom system. The kids no longer smudge and scratch their DVD’s since they are all stored on the drive of the MythTV system. I have a Harmony 890 to control the main system and using my old Harmony 679 in the bedroom. I don’t foresee the need to add DirectTV or cable and because of the draconian measures they are taking to lock out open source systems like MythTV, I don’t even want to attempt it nor am I willing to pay for their efforts. I look forward to more and more media being available directly over the Internet and would gladly pay for a service that provides additional channels in open source standard formats like xvid. Until then I am very happy that I can get all of the major networks in HD digital free of charge. A huge thanks to the authors, developers and community that has helped create MythTV, fantastic work.
