[mythtv-users] Problem with LiveTV Playback

List,

I am having difficulty getting video play back on Live TV.  The screen is
completely black.  What's curious to me, is in the cache directory, I do see
buffer, and I can open the buffer in mplayer, and it plays fine. 

root at mythtv01:/var/cache/mythtv# ls -la
total 564
drwxrwsr-x  2 mythtv mythtv   4096 2006-09-07 10:23 .
drwxr-xr-x 14 root   root     4096 2006-09-02 23:04 ..
-rw-r--r--  1 root   mythtv 565184 2006-09-07 10:23 ringbuf1.nuv

I'm using 2 PVR-250s, attempting to get 1 of them to work at a time
(/dev/video0).  The only line that really catches my eye is:
2006-09-07 10:13:07.227 nVidiaVideoSync: Could not open device /dev/nvidia0,
No such device or address

But I do not have an nvidia device (I have a matrox card), and I can't find
anywhere in the settings that set it to use an nvidia device.  I'm a MythTV
noob, but I do note that something must be wrong with the playback (and not
with the capture cards, etc) because I do see the buffer, and the buffer
plays in mplayer.

Below are my lspci and outputs.

Thanks all for your time,

Matt
