Hey everyone. I've tried to back up a DVD with DVD Shrink, DVDDecrypter, and ImgBrn, and in each case the playback is "jumpy"--there are very brief but noticeable little skips as the payback goes along. Anyone encounter this problem before? I don't think this is the issue, but do I need a dual-layer DVD in my PC? The disc is an NTSC dual-layer. Any help is appreciated.
