Is it a burned copy of a DVD or an original?
Is your DVD drive set to play DVDs from another region (i.e. it's set to play US region and the DVD is some Japanese anime or somesuch)?
My message is: Windows Media Player cannot play the DVD because a problem occurred with digital copyright protection.
The drive reads data. But I can't seem to play anything with windows media player 10. With CF, it just doesn't do anything.
Don't post the same question in mutltiple forums on the same message board. Very poor netiquette, IMO.
