Hmm.. not sure why that bit of code should cause it to get stuck.  If the 
audio is way ahead of the video then warping the audio to bring them back 
in sync would either have to take a very long time, or would be very 
noticably warped, so that bit of code is supposed to extend each frame to 
stay on screen for longer until the audio and video are back in sync (kind 
of an emergency synchronisation system for when things are really bad).  
The only thing that springs to mind is if the avsync_avg value is bogus 
and very large at some point then it would freeze the video for a very 
long time.  I'll add some sanity checking in to clip large values when I 
get time to play with the code next (probably next weekend) and see if 
that helps.
