With my most recent patch, mencoder would skip 1 or 2 frames from
somewhere within the first couple seconds of an encode in order to
compensate for decoder delay.

How about using dwStart in the AVI header to delay the other streams? I
should be able to add that to muxer_avi. I'm not sure about the lavf AVI
muxer, but I ought to be able to fit it in somehow. Are there any other
muxers that can/should be adjusted in a similar fasion?
