Indeed there is a new parameter, and apparantly my dependency 
information didn't cover system headers. So it recompiled the new jitter 
buffer, but never recompiled the buffering part of my application before 
linking. I tested my "simulate packet loss" mode and it couldn't recover 
from that. (It did work with zero loss however.. odd).

Once I updated the application to use the updated function call, the 
jitter buffer worked again, giving sane results even with +/- 30 ms 
arrival times and 20% packet loss. So sorry for bothering you with a 
bogus bug report :(

Best wishes,
