A freind recently gave me a DVD-R disc with a movie on it (he made it himself). The DVD will run on my PS2, except it is in black and white. I tried to run it on my PC but the disc isn't even detected! I try to browse the CD-Drive but it says that no disc is inserted. The strange thing is that it once found the disc and I could watch the movie fine. After a reboot the DVD wasn't detected again and I have no idea what is wrong. I don't think that scratches on the disc are a problem although there are a few minor ones on it.

I also have a trial installation of Intervideo WinDVD 5 which of course is need to watch a DVD.

Please help me!

Thanks.
