I have a now old Sony Handicam, about halfway between never twice same 
color and modern hidef, its mpeg output is quite compressed, but a 22 
minute wedding is 30 G's of raw video. I had to use kino and edit pretty 
heavily to make it fit on a single layer dvd. An sha1sum would have been 
around 35 minutes on this machine but that was nearly 20 years ago on a 
500 meg K-III cpu.

Cheers, Gene Heskett.
