Hello again, Thanks for the input on my last post. But one thing i noticed was if I were to upgrade my mac book pro's disk space i would be out of my warranty... which would not be good.. so I decide to just purchase an external memory drive. Anyway herse the thing guys. The reason I split my disk drive with windows and Mac OSX 40 by 40 gigs. was that many Korean programs or foreign programs only have windows platforms so If I am I would need windows. But the thing is I have noticed the program I use to download many movies is also available on MAC. So I need your unbiased opinion. Are movies run more clearly and smoothly on the Mac's quicktime or should I just stick with using windows for movies and Mac for music and school stuff etc. Is Mac well compatable with movies downloaded online?
