[mythtv-users] Jumpy video with a PVR250

[Jeff volckaert]

Hello Everybody,

I posted this on the IVTV mailing and haven't gotten any replys yet. 
I thought I would post it here to see if anyone has had a similiar
problem.

I have been having a problem with jumpy video and audio ever since I
wiped my box a while back. I am using a PVR-250 I have had for a
couple years now. I had FC3 running fine with Mythtv and had to wipe
the box for other reasons. After the wipe, the video was jumpy. It
didn't matter if I tried the stable 0.2 or unstable 0.3.

I recently wiped the box again when FC4 came out to see if I could get
a clean slate on it. The problem is still there. I am using the
recommended firmware (pvr48wdm_1.8.22037.exe) and the latest driver
(ivtv-0.3.6w).

Any help/thoughts? Anyone know how to capture a single frame so I
could post an example?

Below is some spew from my log.

Thanks,
Jeff
