<div>Ok. That was my mistake. I grabbed the first number out of
my Xorg log file which evidently is some generic class. Further down I
see that the card is a Ge Force 9500GT.</div>

<div>In that case, run your frontend with -v playback in a console
window and be sure VDPAU is initializing properly. Also, what
deinterlacer are you using? I've only had VDPAU problems when I tried
to use a deinterlacer (Advanced x2, etc) that was beyond the
capabilities of my card</div>

I have had a chance to do some more investigation without interfering
with the TV-watching household and have come to the following
conclusions:<br>
1) There is nothing remarkable with the -v playback. VDPAU seems to be
initialized properly.<br>
2) I was not using any deinterlacers. My TV is set to 1080i
(1920x1080) and 60 Hz. For grins, I tried several of the deinterlacers
and there was no marked improvement.<br>
3) I cut the number of vdpaubuffers from 50 to 20 and the stuttering
got much worse. Increasing it from 50 to 80 to 100 made no difference.<br>
4) The jerkiness or stuttering seems to be contained in a single show
(Two and a Half Men) and only to the older shows that were transmitted
in SD.<br>
5) Most all of my other recordings are either 720p or 1080i. There
doesn't appear to be any stuttering in these recordings.<br>
6) That leaves only the video/audio sync issue described in my first
post (video goes about 2x while audio stays at 1x; push a skip or pause
action and all is well) that affect all recordings (and videos).<br>
7) I played an SD episode of 2 1/2 Men with an external video player
and it played smoothly.<br>
<br>
So, the problem was not quite as bad as I made out; just that we watch
an episode of 2 1/2 Men each evening so it sticks out in my mind.
Maybe someone with more experience with video decoding than I have can
give an explanation even if there is no fix.<br>

I have problems with Two and a Half men also..If the program is
recorded off my STB (SA4250HDC) it works fine..If it's recorded of my
digital card it's blocky and the audio screeches.. One other thing I
have noticed is this always happens on The CW station,if it's off CBS I
never have these problems.. This makes me think my problem is with the
station and not Mythtv..<br>
