I was also a blue screen recipient and I ain't gonna touch SP2 until it's necessary..
Also as I use Pinnacle Studio 9 that's another reason not to install it. Microcrap even have a page on line that tells you the programmes SP2 can and will fuck up. It was posted here originally but I lost it when I had to re-format after the first SP2 install.. DUH
Found it in time to edit this post:
