I tried backing up a movie called Stone Aged. when I used power dvd to view the movie, I get a green screen, but I can only hear the movie. I thought it was just Power DVD that wouldn't play the movie, so I went on and back it up using CLONEDVD. After it burned I put the movie in my DVD player same thing (green screen, just can hear the movie. Its an orginal movie. The movie plays fine in my DVD player but not my DVDROM. Its acting like I need a codec but its a store bought DVD movie, doesn't make any kind of scence that I would need a codec. Has anyone else had this problem before?
