DVD drive not reading certain DVD's
I have this strange problem that is very frustrating and nobody seems to now exactly what is wrong. Certain DVD's that I own such as Shrek, Crouching Tiger Hidden Dragon, and The Deer Hunter will not work on my DVD drive. When I put them in they just don't appear at all. If I go to My Computer it shows no disc in the drive and if I try to click on the DVD drive it asks me to insert a disc. All of my other DVD's work fine. The strange thing is that the DVD's that don't work will play perfectly fine on a regular DVD player.
About the only thing that even remotely sounds like a possibility is that the DVD drive I have for some reason won't read certain types of multi-layer discs. The only other thing I can think of is that maybe my drive is dirty, but then I don't understand why all of my other DVD's would work fine. It's very frustrating because I just went out and bought The Deer Hunter tonight only to come back and find that I can't watch it because of my stupid DVD player. I have the Pioneer 16x tray load DVD player. It's suppposed to be a good one apparently. I'm also running XP pro (the rest is in my sig.) Anybody have any idea on this one? Thanks :)
