When i try to play any (even factory burned) DVD movies. the sound is very stuterie sounding. and the picture is the same jumpy all the way through the movie. Every movie! I just tried to play a music CD in it and it sounds choppy too. not as bad as the DVD movie. and it does not matter which media player i use it all the same. Do i have a setting set wrong maybe? i don't remember changing any.... unless by accident. I need some help!!!
