Unusually DVDs work fine on my computer. It prompts me and I select Realplayer. Sometimes it doesn't prompt me, and I just open up RP and it works fine. But some DVDs wont work at all. When I try to access the drive it pops up with a message saying something like "Cannot access. The disk may be corrupted or is using a format incompatible with Windows." .... Something like that. But here's the thing. When I put the DVD in my cheap DVD player it plays fine. What's the deal with that? I think the drive is a Toshiba DVD ROM. Is there anyway to get around this? There must be. If my DVD player plays it my computer should be able to. What am I doing wrong? I downloaded AnyDVD. I haven't bought the program yet, but it's supposed to have an evaluation period. Well... it's running, but the DVD still doesn't work. I tried VLC player, Realplayer, and some other player. It still wont play even with AnyDVD. I would totally buy it if it worked, but I don't want to buy something that isn't going to fix this. Did I not set up AnyDVD right, or do I need something else?
