I backed up an episode set of discs. When I did each disc I split the episodes onto separate discs to keep 100% definition. I used Anydvd 6400 and Clonedvd 2915. The backup discs play perfectly in my standalone dvd player. When I put the first disc in my computer, it plays perfectly. When I put the second disc (from having split the disc) in, the computer will not recognize that there is even a disc in the player. Unfortunately I do not have a lot as those have been deleted already. Does anybody have an ideas? I have not had any problems before. However this is the first time I have split a disc onto two discs.
