And beside...if the movie companies really want to stop the bootlegging of movies, they should take a close look at who they are sending their "screener" tapes and DVD's to. Most of the boots out there now are of pretty high quality and are being leaked to the file sharing networks from people with access to prints and digital copies of the stuff.
How long does it take to download a DVD on DSL or cable-modem? A DVD is 7+ GB and high-speed DSL (over 700Kb/sec) is just able to do video (TV quality) in real time. Most people still have 56Kb/s dialup!
Downloading quality video is still a long way off, or a job for very patient people. You could go to the video shop, rent the movie watch it and return it before the download finishes!
