Did you enable xvmc in the /etc/X11/XvMCConfig? It should have the below in it.

Thanks Scott! Unfortunately, I'm now discovering some problems. Live TV works great, but recorded TV doesn't work at all. The first problem I ran into was the NIC overrun problem. It looks like in Ubuntu 9.04, this can be fixed by: sed -i -e "s/^# kopt=root=UUID=.* ro$/& processor.max_cstate=2/" /boot/ grub/menu.lst update-grub Also, I forgot to include setting the frontend's playback settings as indicated here: http://code.google.com/p/atv-bootloader/wiki/mythtv Note that these settings didn't work perfectly for me. The OSD did not appear and I wasn't able to change channels on live TV. Setting the OSD Render to Chromakey fixed the problem (even though the log shows an error that it can't find chromakey, whatever it falls back to works fine). I've tried setting the renderer to both ia44blend and chromakey, neither made a difference in fixing the playback of recorded TV. Changing the Video Render to Standard (ffmpeg) didn't work either. In all cases, I simply get a black screen. Here's an applicable section of my frontend log file (using Standard XvMC, xvmc-blit and ia44blend): 2010-08-29 11:27:56.541 NVP: prebuffering pause 2010-08-29 11:27:57.569 NVP: prebuffering pause 2010-08-29 11:27:58.641 NVP: prebuffering pause 2010-08-29 11:27:58.962 TV: Attempting to change from None to WatchingPreRecorded 2010-08-29 11:27:59.086 DPMS Deactivated 2010-08-29 11:28:02.394 AFD: Opened codec 0xa10ba90, id(MPEG2VIDEO_XVMC) type(Video) 2010-08-29 11:28:02.394 AFD: codec AC3 has 6 channels 2010-08-29 11:28:02.397 AFD: Opened codec 0x9cbd800, id(AC3) type(Audio) 2010-08-29 11:28:02.397 AFD: codec AC3 has 1 channels 2010-08-29 11:28:02.399 AFD: Opened codec 0x9bb43e0, id(AC3) type(Audio) 2010-08-29 11:28:02.421 AFD: Opened codec 0x9c98b60, id(MPEG2VIDEO) type(Video) 2010-08-29 11:28:02.443 Opening audio device 'default'. ch 2(2) sr 48000 2010-08-29 11:28:02.452 Opening ALSA audio device 'default'. 2010-08-29 11:28:02.604 AudioOutput Warning: Mixer attach error -2: No such file or directory Check Mixer Name in Setup: '/dev/mixer' 2010-08-29 11:28:02.948 VideoOutputXv: Desired video renderer 'xvmc- blit' not available. codec 'MPEG2' makes 'xv-blit,xshm,opengl,xlib,' available, using 'xv-blit' instead. 2010-08-29 11:28:02.962 VideoOutputXv: XVideo Adaptor Name: 'NV17 Video Texture' 2010-08-29 11:28:03.581 OSD Theme Dimensions W: 640 H: 480 2010-08-29 11:28:08.591 Realtime priority would require SUID as root. 2010-08-29 11:28:08.036 TV: Changing from None to WatchingPreRecorded 2010-08-29 11:28:10.186 FilterManager: failed to load filter 'none', no such filter exists 2010-08-29 11:28:10.186 Couldn't load deinterlace filter none 2010-08-29 11:28:10.310 [mpegvideo_xvmc @ 0xb6bf5744]get_buffer() failed (1 1073741824 2 (nil)) 2010-08-29 11:28:10.310 AFD Error: Unknown decoding error 2010-08-29 11:28:10.322 Video timing method: USleep with busy wait 2010-08-29 11:28:10.336 [mpegvideo_xvmc @ 0xb6bf5744]get_buffer() failed (1 1073741824 2 (nil)) 2010-08-29 11:28:10.347 AFD Error: Unknown decoding error 2010-08-29 11:28:10.352 [mpegvideo_xvmc @ 0xb6bf5744]get_buffer() failed (1 1073741824 2 (nil)) 2010-08-29 11:28:10.352 AFD Error: Unknown decoding error 2010-08-29 11:28:10.361 [mpegvideo_xvmc @ 0xb6bf5744]get_buffer() failed (1 1073741824 2 (nil)) 2010-08-29 11:28:10.361 AFD Error: Unknown decoding error 2010-08-29 11:28:10.366 [mpegvideo_xvmc @ 0xb6bf5744]get_buffer() failed (1 1073741824 2 (nil)) Any suggestions would be greatly appreciated! I'll update my guide above once I get these quirks worked out (can you edit a previous post?).
