I think you would be better off resampling your tiffs to a lower resolution
as reading a series of tiffs will require less processor power (at lower
res.) where jpegs require decompression.  My impression was that when you
create a Quicktime movie the files are converted to BMPs anyways so
resampling would be your best bet for speed.

My two cents.
