I just received my BB DVD's and I am unable to play all of them except the timesaver dvd. I can play the push-pull (from play program only) but when I play the superset it will let me see the introduction then I get a message saying "error from disc...please check disc. I get the same response when I play the KPC/LEG $ GLUTES dvd and the Step,Jump and Step blast dvd. I can't even get to the introduction. I know that sometimes the dvd player may not be compatiable but I would hate to have to purchase another dvd player just to workout. I can play all of the other Cathe Dvds with no problems. I have already e-mailed to SMN, but just wanted to know if anyone else has that problem, or maybe any suggestions. P.S If I do decide to buy another DVD player what features should I look for. Thanks.....Chap
