I am in the process of having a PC built.... Intel Core I7 920 quad with the forum input... last year I bought the pro pack upgrade Platinum movie studio 9 + DVD4.5.... I didn't even open the software as my PC is too weak to install it.... I have a choice of getting windows XPpro installed or Vista.... which I read is a pain.... windows 7 coming at the end of the year.....so which OS should I get ? Does movie studio 9 works better with XP?
