Hi Bernie,
I had to recompile (re-emerge in Gentoo) mjpegtools with quicktime and
dv included (with -f a the file size was over 2 Gig). Looks like I had
the right idea but not the precise way to get there. Followed your
instructions, but still not finshed. Note, I had to add -n n parameters
to the yuvscaler because it did not recognize the format. Here is the
problem:

The original video excap0001.avi is 753 MiB
The video_without_sound.avi is 5.7 GiB (same as with -a a)
The sound.mp2 is 174 MiB
Why is the "Error in WAV header"?
My audio.wav file is 1.1 GiB
