I think you need to understand what this is really about. Dexter is absolutely right, technically, but it is a temporary solution he suggesting, looking over time. Microsoft is well known for this, and the real reason is that Microsoft is colluding with other companies, as Adobe or Intel, to force you to upgrade, and of course paying them more money. It is a sort of scam and cartel using technology as a leverage to extract money. There is absolutely no reason at all this should have to happen, if the software wasn’t written in the first place to create the problem to get more money off you when you are forced to upgrade to W7 and next generation Adobe. The long term solution is to go to another program, not Adobe, and those exist, and preferably to another operating system as Linux. Start using a better setup as a Live CD as Puppy Linux and Cinerella. You start the computer from the CD (or hard disk if you set it up that way) and the entire computer is dedicated to video editing, not with hundreds of useless not needed processes in the background. Try it, it is free.
