I need some technical assistance, someone who knows their stuff... My question is that my 2004 Grand Caravan SXT came with a factory 6-Disc In Dash CD/DVD Rear Seat Video System with Wireless Headphones (RF); 2nd Row Overhead 7" Video Screen and Video Remote Control. The DVD player plays regular DVD's but WILL NOT play copied DVD's (copied using 321 Studio DVD X Copy software onto DVD-R discs). I get very choppy audio and video playback. Can anyone explain why this is happening??????

 

My moms 03 DGC does play burned DVDs.
