[mythtv-users] XvMC output not working

[T.P. Reitzel]

I, too, really need XvMC working. Currently, I'm using an el cheapo ATI 
Wonder VE for my tuner. I know. I know. ;) I'm also using an el cheapo 
PC, 1.2 GHz Celeron, with no AGP. My videocard is an nVidia GeForce FX 
5200 PCI. My audio card is a Turtle Beach Santa Cruz. MPlayer 1.0 pre 7 
plays MPEG streams quite nicely through nVidia's libXvMCNVIDIA. The CPU 
utilization hovers around 30% for a DVD through MPlayer. As far as 
MythTV, I tried v 0.81.1 which didn't really work with the 
aforementioned setup and XvMC. I had constant lockups. As far as SVN 
pulled last night, MythTV still has constant lockups with XvMC. However, 
XvMC through nVidia's libXvMCNVIDIA interface seems to actually work 
now. The video stream rarely hesitates at all during playback, but the 
lockups continue. I notice that the video stream plays for about a 
couple of minutes before hardlocking the PC. I can see hear the audio 
stream, but the PC requires a hard reboot. The process never fails. I've 
tried various combinations in the Playback options for the TV Settings, 
but the result is the same - lockup. Am I overlooking some setting or 
are the lockups due to an incomplete implementation of XvMC in MythTv or 
nVidia's driver?
