I have seen the same problem on german channels - but not on all, and I 
found a common sense:
- channels with MP2 audio: sync ok
- channels with AC3-5.1: sync ok
- channels with AC3-2.0: not always in sync, playing back and forth 
helps, there also seems to be a drift over time

I am using yavdr 0.1.1 (http://www.yavdr.de) which also includes XBMC 
which is not based on xine. I haven´t seen any sync problems here so far.

With kind regards
