Man, I hated those early days of video piracy. 500 meg download for a movie that was like 320x150 pixels and absolutely horrible quality. Which you had to delete, cause you didn't have all that much space on a 5 gb hdd.
500MB really isn't that terrible for a feature length film. I've got a bunch of films released on 500MB PSP discs and they look great. You're probably just spoiled by the ultra hd and master audio thats on modern home releases.
