I used dvdshrink to copy the dvd to my hard drive, then used the dvd burn software that came with me Sony 8x DVD+-RW drive to burn it to Memorex DVD+R 8x disks. Memorex seemed to be one of the more expensive disks, so I'm wondering if its a dvdshrink problem or what. It plays some of the copy fine, and parts of it freeze up or go slow-motion. I've tested 3 newer model dvd players of Various brands that all claim to support DVDR disks. Before I go out and buy the Pre-court version of a dvd burning software ($100 on ebay) or spend money on dif brand disks I was wondering what is the real problem in your opinion?
