I am using DVD Shrink 188.8.131.52 with my Gateway Pentium IV. I have an external TDK 12X single layer burner. I have two HD-DVD players that I play back a majority of the movies. I find that my Samsung gives me more errors than the Toshiba does. However, they both, on certain disk create jumps that happen more frequently towards the end of a movie until the movie just freezes in the DVD player, and the DVD player starts the movie again. I personally think that I might be doing a couple of things wrong. I think that I might be burning the movie too fast, and therefore, I am starting to burn them at 4x rather than 8 times. I also wonder if it is the source dvd that is causing me problems. Any advice would be greatly appreciated.
