I have some DVD discs (probably recorded on a stand alone DVD) which WinXP Pro doesn't seem to support!?
It's says unknown format. DVD Decrypter says it's an I/O problem etc..? and WinDVD and PowerDVD doesn't work either.
One of the media are Maxell DVD-R 4.7GB. All these discs plays well in my stand alone DVD player.

Can anyone help me out here? Thomas
