I have successfully ripped a DVD using DVD shrink. Playback in PowerDVD from the hard disk is absolutely perfect. However, when I burn it to a DVD using NERO classic (Mode 1 ISO9660 joliet diabled) the playback from the DVD is blocky with pixels breaking up and very jerky. The picture will freeze on my DVD player more than on the PC. Has anyone seen this before ?? I have tried using two different types of media with no discernable difference. Burner is a MSI DR-4A which I have upgraded the firmware to 3.1, came with 2.17. OS is Win/XP, Athlon 1900, 256MB DDR RAM.
