I have several of Cathe's workouts now on DVD: Intensity Series, BB Series, Slow & Heavy, CTX Series they all play fine, wonderful, groovey on my DVD player. Yesterday I received the Classics DVD and tried to preview it. The player read the disk--I got the copyright warnings and the main menu came up, but when I pressed play, nothing happened. I tried each of the three workouts and nothing would happen. Then I tried playing the "heart rate check"--THAT played! I then decided to go the chapters section and played the warmup--the whole workout played. I was half way through the second workout, then it just stopped! Froze, wouldn't play any more. I ejected the disk to check it, it was clean, put it back in then I got an error message that that disk couldn't be read in my player. I gave up and decided to preview the bonus combo on the Pyramids DVD...that played fine until I got to the streching--my picture started breaking up to the point where you couldn't see what was going on any more. While I've never watched the bonus combo before I have used that DVD many times to to the Upper and Lower Pyramid workouts. So, this is a long way of asking, can a DVD player go bad...does it (the player) need cleaning? Should I chuck it all and by a new Sony DVD Recorder?
