I used dvdshrink and then used dvd decrypter to make a back-up of my dvd's. It said burn was successfully completed but now the disc will not play in my computer or dvd player. I use dvd+r discs. I've had all kinds of problems with dvd xcopy so I heard this was a good way to make back-up copies, but I can't get the burn copy to work. Any suggestion? Thanks I also tried burning with nero but then I had a finalizing error so I tried decrypter and it said it was successful but will not play.
