I am copying dvd movies. I am using Dvd Shrink and cloneDVD. I first use DVD shrink to create the ISO then I use CloneDVD to burn the ISO.

I am able to rip the dvd to my hard drive and burn it with clonedvd.
I am able to play the burned dvd on a dvd player BUT I can't play the dvd on my computer using Powerdvd,WinDVD,DirectDVD etc... The software just freezes.

what do you think is causing this problem. I am using good quality dvd+r, my pc supports this format.
