[mythtv-users] "Video Too Fast" Playback Problem

Hey folks,

I used the 10.04 release of Ubuntu as an occasion to upgrade my FE/BE
machine to Ubuntu 10.04, then installing the mythtv packages,
release-0-23-fixes (24158).

I'm having an issue playing back my movie files in that the video is
going way too fast...something like double speed.  The audio sounds
fine, and of course very quicky lags behind the image.

Googling has found several incarnations of this problem, and I've
tried the solutions I could see; switching the time stretch to
something other than 1.0, and switching it back; also changing the
Video Playback Profile around (it defaults to CPU+), but this doesn't
seem to make any difference.


I've included the front end log when I start a video (then stop it).
There are some errors reported, but I don't know to what extent
they're relevant (a VDPAU error, for example despite not having an
nvidia card, or using a VDPAU profile).

Any insight would be greatly appreciated...I've been running fine on
8.10 with 0.22 for a while, but would like to move forward to take
advantage of the new goodies.

Cheers.
