I have two problems with playback:  
First main problem is audio sync, which while playing a recording the audio slips further and further out of sync after 5 or more minutes.  Then the video skips to catch up and I get a gap in the program (very disconcerting when you're trying to follow the programme!!).  These skips seem to occur coincidentally when console messages say "buffered 6.3 frames (v:10.9, a:6.3)"

Second problem is more similar to several other people, and possibly yours, where if I FF/REW a playback, when I hit play again it jumps "minutes" making FF/REW very inaccurant.

  I experience the audio sync problems when I fast forward or rewind recordings, or when I press green/yellow (jump 1 minute back/forward) or press 7 or 9 between markings, this is however the problem with xineliboutput. Only way to fix playback audiosync is by pressing the red button (jump to a specific time). All the xineliboutput versions seems to do this and, xine-lib-1.2 also does this. problem must be with the plug-in it self and similar to yours?

      I wouldn't bother upgrading, to be honest.

      I've had several attempts to upgrade to 1.7 and VDPAU - but consistently get audio/video sync problems with live video and issues with indexing during rewinding/forwarding during playback.  Have spent more hours than I care to say trying to fix this, only to downgrade again.

      vdr-1.6.0 and xine-0.8.0 work just fine for me!!

    To be fair to my comment above, I've had audio sync problems with live TV on all versions above vdr-xine-0.8.0 which is why I've never been able to run a newer version in production.  I've had several posts on this and tried everything anyone has suggested - but after an hour or my wife banging on about the poor quality, always downgrade back to VDR-1.6.0 and VDR-XINE-0.8.0

    So I don't think my problems are related to VDPAU or VDR-1.7.x.
