Problem : MYTHTV Player picture quality/performance pales in comparison to MPLAYER
First my setup : I have an Athlon 64 3500+ system with 2 x HD-3000 cards, and an NVIDIA 6600 GT PCIe card, running on Fedora Core 3, kernel 667, NVIDIA driver 6629, and a recent Xorg (to fix the video problems). I have been monkeying around with the HD cards for weeks and finally have all that nonsense worked out. Now I have MYTHTV installed from CVS02062005 RPMs off ATRPMS . Installing went fine. Everything currently works, I am recording all the HD content I like. NVIDIA's driver currently has trouble with outputting to HD without some 'rigging' so I picked up an Audio Authority 9A60 transcoder and set video to output to 1280x960 . This allows my picture to fix fairly nicely within my Toshiba 50HX81 HDTV boundaries. Now, on to the problem : If I use MythTV to view my recordings (haven't bothered with really testing live TV), playback is smooth, but anything in the screen with decent motion suffers from poor up/down conversion and creates lines of blocky picture (see ATTACH PHOTO as sample). I assume this is caused by XvMC because after searching many threads I found that if I run 'export NO_XV=1' before running MythFrontEnd, the blocky lines go away, but is now replaced with general frame drops. Also, I had to turn on audio buffering because I was getting some ever so slight stutter in both modes. Now, if I take the same video, and throw it at mplayer directly, I get smooth seemless playback, including audio. I've has my Xorg set to display @ 1920x1080i and still mplayer worked perfectly but MythTV's player had troubles. So, my question : Is there anything I can do to fix this? I've already set my mythfrontend to chmod +s , but that didn't help. Help. If nothing else, can an option be added to view recordings via an external player while work (if any) is being done to improve the speed of the mythtv player code? -Ackster
