8 bytes? Nope, 24 bytes. And I was talking about total avi overhead,
not the additional overhead compared to 24000/1001 time base. So I
guess the correct number is 10 megs per hour, or something like that.
Sorry my original estimate was off by that much.. I thought I'd
calculated it before and gotten something like 50. Maybe the 50 was
for vorbis-in-avi with this same method..
