I have an NEC 3520AW burner with liggy and dee's 2.U3 firmware, and recently whenever i burn movies there is a skip/freeze somewhere in the movie. Sometimes one sometimes two sometimes three. The audio/video will freeze for a few seconds and then pick up a few seconds later in the movie. I have tried different software, different media, different burn speeds, different firmware. If anyone can suggest something it will be greatly appreciated, otherwise im saying screw it and getting a plextor.
