I started using DVD Shrink to back up my DVDs. After a few successful copies, suddenly all DVDs I burn when replayed in the home DVD player, the image freezes about every two seconds. I then used other sw, like Decrypter, Sonic MyDVD (in this case making DVDs from VHS tapes), and got the same results. Since I didnt change the DVD media I suspect there is something in the configuration of the system. I use Windows XP, 60 Giga HDD, Sony DRU-530A DVD burner, 256 Mb RAM. Any help is greatly appreciated.
