hi everyone.... i just backed up my copy of "Collateral" twice using Mac the Ripper 2.5.6 and Popcorn. the rip and burn were both successful. i didn't get any error messages but when i played it back on my dvd player, every few seconds the video stutters. when i used mac the ripper, i did a full disc extraction and compressed and burned using Popcorn. after the 1st burn showed this stuttering, i tried it again but this time i used full disc arccos extraction and compress and burned using Popcorn. i popped it into my dvd player and the video is still stuttering. am i doing something wrong? what can i do to prevent and stop the video from stuttering? any ideas and suggestions would be greatful.
