5x is perfectly fine for playing movies, the issue is more how well the actual xbox plays movies, it depends on the software they use, which i dont know anything about. i hear lots of critisism about the awful playstation2 dvd playback, but i'd expect xbox's to be better.
if you really want the dvd experience go for a proper DVD player with a good TV and quality speakers. a friend of mine has a £700 ($1000) dvd player, £500 TV, and B&W speakers that cost almost as much as both those together. But then hes mad
"i dont know what you're listening to me for, havent you figured out i dont actually know anything?"
