Oh. Try this: -ao pcm -srate 8000 -channels 1. That will make the
output very small during the first pass so it won't waste disk space,
but a/v will still sync. Unfortunately you have to waste a little cpu
time decoding the ac3, but this should be done for proper a/v sync
anyway since -oac copy won't catch broken ac3 frames.
