This Christmas DVD

For some reason the DVD Title This Christmas is not being recognized on my computer, it plays in all of my dvd players but when I attempt to make a backup copy using DVDFab decypter HD 5122 or ripit4me or dvd decypter or dvd shrink my computer will not recognize the disk or allow me to open or explore the contents of the disk, it tells there are no files on the disk or that there is no disk in drive. I have made backups of other disk with no problems and continue to but the dvd This Christmas is the first time I been unable to make a backup or even play the DVD on my computer. Thanks

Piece of cake with this one! Gotta be the disc.
