I have been having the same problem - it's only happened recently (past
couple of updates to 0.24-fixes) - juddery video and audio, on HD-PVR
content in the Recordings directories ONLY.  Other HD content (HD-HR
recordings and all "former" recordings - those which I've processed via
ffmpeg and avidemux and now view via MythVideo - work fine).

I do *not* have any of those VDPAU pre-emption entries in my frontend log
after trying to play one of these files.

Anyone have a fix yet?

I don't THINK it's the video drivers, but I *have* had major problems with
the last two updates of the 256 drivers - running them through dkms as
part of the upgrade process makes the machine unbootable (full-on kernel
panic, two different kernels) - VERY odd - I've had to manually restore
the "older" 256 drivers and initrd files from my backup, whereupon I can
again run normally - but still have the above problem with the HD-PVR
recordings.

"Curiouser and curiouser".  I know this install (combined BE/FE, Ubuntu
10.04, JYA's Myth repos) is getting stale, so am working on setting up a
fresh install soon (when I have time).  In the meantime, it'd be nice to
fix this HD-PVR issue.

Thanks
Bob
