I'm just looking through the xine code at the moment (for other 
reasons).  They seem to have something they call the "metronome" which 
basically calculates their own timestamps based on all available info, 
eg the timestamps in the mpeg stream.  Specifically this is to deal with 
timestamps which wrap or go negative, etc.  Interesting idea...
