Michael, I'd like to repeat that on stream copy, in *most* cases (that 
is as long as the extra size due to the stride of the original file is 
not mistaken for a palette, and that can only happen if the extra size 
is exactly 1024 bytes), the destination file will have the correct 
stride thanks to ff_reshuffle_raw_rgb(). Thus, it won't be a perfectly 
identical stream copy, but that would be rather useless anyway due to 
the different stride requirements for AVI and QuickTime.

Example: ffmpeg -i 8bb_129.avi -vcodec copy 8bb_129.mov

Mats
