What would cause the movies that i have ripped and copied to skip during playback. I use shrink and burn with nero. I always reauthor and only burn just the movies without all the extras. I started by using 4x dvd-r and it seems like most of those are fine but some of the 8x blanks have some skips in them. I always burn at 4x speed so that will leave less room for errors. I never get any errors during the encode process and no errors during the burn process. HMMM its just aggrevating to find out after the whole process then i watch the movie and it doent playback correctly. HELP PLEASE!
