I have Shrek 2, I don't remember being forced to watch all this junk, though I do remember a Shark Tale trailer but I usually just punch up Menu and the title screen comes up. Forcing people to watch crap when they dont want to is a BAD business practice that will backfire, imo.
Disney, of course, is the biggest offender but I can still hit the Menu and be rid of it all, in most cases. I think the DVD player has alot to do with it as well.
Of course. On my DVD player you wouldn't see fifteen minutes of commercials, or the title screen or even the FBI disclaimer, it shoots straight to the start of the movie, because of the "Auto Play" feature in the options menu.
