I recall my computer notifying me of a software update a few weeks ago, since it's been downloaded and installed I've noticed a couple of weird bugs. My computer occasionally doesn't load images on the internet, and whenever I load a DVD disc into my Superdrive the computer freezes and a gray translucent box comes onto the screen saying that I need to restart the computer. Anybody know of anything in particular that causes something like that? I don't mind the image problem so much as the DVD problem. As soon as the disc is in and the drive spools up the computer freezes and I have to manually restart it.

I would appreciate it if I could get some help about this. I've been backing up my DVD collection onto my computer...or at least attempting, since I ripped the first DVD (which went perfectly well), my computer has been acting strange with DVD's. I'd appreciate any help you can give, thanks.
