btw do you use autoquality ?

The problem is that you can't drop frames between keyframes without
decoding them - as all the following images gets broken.

very unusual behaviour :(
Hard to know why - maybe you are another one with not very precise
audio card ?? (type ??)
The code which would meassure the precision of audio crystal is still
no in the avifile source - so you will have to wait for this update
if your card is drifting in time (though its quite unusual this
would happen only while your system is under full load)
try to send me output of:
export AVIPLAY_DEBUG=1
aviplay yourmovie.avi

Resistance is futile. You all will be packaged
