Ok, I tried to duplicate the no audio sync problem w/ my two test files,
and now hte problem has gone away. The only thing I can correlate to audio
sync working is that I clicked the "Dropping frames" button, in "Video"
configuration, off. However, if I turn it back on, the audio still syncs
up. Just as I said that, I suspended aviplay while it was playing and
then stuck it in the background, and now the sync is off again. Now I've
stopped playback (typed 'x') and restarted it (typed 'v') and the sync is
back. How's that for mixed results?
