I have Windows XP 32 bit running under bootcamp on my early 2008 Macbook Pro. I think the problem started last week, when I was burning about 4 isos on 4 different DVDs. Then after that I wanted to watch a movie on a dvd while I was still on Windows, but whenever I start the movie the mouse pointer would move slowly and the movie would get choppy. Even when I'm transferring files from a CD to Windows the files would take longer than usual to finish copying. So I switched to Mac OS and tried playing the movie again from the dvd. When it played I noticed that it's playing normally and it's not a hardware issue that I'm having. So I thought that the problem was gone and I should check if the dvd would run smoothly on Windows like it's running under Mac OS. But when I tried it on Windows the problem was still there, the dvd is still running slowly. So anybody know what's causing this problem?
