My college requires that I upgrade to SP2 and I have noticed that it is causing problems with my DVD Drive. I can open CD's and normal DVD's, but I cannot view anything that I have recorded on a DVD-R and I cannot record to a DVD-R. I have tried uninstalling SP2 and reinstalling, seeing if the drive had any updated drivers and even tried installing all the updates for Nero 6 Ultra Edition. I'm curious to know if anyone else is having this problem or if anyone knows how I can resolve this problem. Thanks alot.
