I have had some problems with certain movies copies - Flyboys, Barnyard, are 2 - freezing at around 17 seconds. Nothing but a black screen. If you let the dvd continuing playing in the dvd player, it does not look like it is doing anything and for 2 to 3 minutes you are stuck at 17 seconds on the player and nothing but a black screen. 2 or 3 minutes later, the dvd will finally start playing. Annoying as can be. Any advice? Is this a copy protection problem? Should I scan the rip on the harddrive for errors before burning?
