Right, question for you tech-heads out there.

My PC has a DVD-RW drive. It plays CDs fine. It plays my PC games fine. But lately, when I try to play some DVDs, I have a problem. The drive whirrs like it's reading the disc, but then nothing happens. It might whirr a few times, but still nothing. When I open the My Computer page to try to access the DVD manually, it shows no DVD to read. When I check through Windows Media Player, it says "cannot detect a DVD in your drive".

But the thing is - it works for some DVDs. It's mainly newer ones that are affected - so I'm thinking there might be conflict between the copy protection on the newer DVDs or something and the fact that I have an RW drive.

How can I check to see what exactly the problem is, and circumvent it?
