Numerous video stuttering and sync issues

[thecapsaicinkid]

I'm going crazy trying to sort out what I think are numerous separate playback issues.

Firstly my system;

Boxee v0.9.21.12563M
Ubuntu 10.04 64bit
Nvidia driver 195.36.24-0ubuntu1~10.04
Xorg.conf is the very basic one regenerated by nvidia-xconfig
nvidia-settings cleared


Different videos exhibit different problems influenced by my refresh rate 50 or 60Hz (as noted) and some issues are apparent in other players i.e VLC where noted.

DVB-T recording played as a regular file
Boxee 50Hz = stutter after 10min, audio out of sync
VLC 50Hz = fine

DVB-T recording played through Boxee MythTV source
Boxee 50Hz = audio drifts out of sync and never catches up
Boxee 60Hz = fine
VLC = fine

HD MP4
Boxee = fine
VLC = fine

R2 DVD
Boxee & VLC 50Hz = consistent stutter every second, noticeable in panning shots
Boxee & VLC 60Hz = intermittent but infrequent audio breakup and random stuttering

R2 DVD iso rip
Boxee 50Hz = fine



Any suggestions welcome.

Thanks

Do you have libvdpau installed?

I'll check.

Here are my guisettings

If you've directly modified the guisettings.xml file (e.g. not through Boxee) then it might be best to start fresh until you get your playback issues sorted out.

libvdpau1 0.3-2build1

I don't think it has been modified outside boxee. I'll rename it out the way and do some tests.

Hrm... well, I've done the obvious bits -- someone with more experience with the Linux version will hopefully chime in now
