I just recently upgraded my DVD player to the progressive 5700. I have been playing it constantly and came across a problem with one DVD. I tried to watch Gladiator and kept getting a disc error. I tried the accompaning "extra" DVD and it played. The problem disc plays okay in my Tosh sd3205 and was wondering if there might be a problem with the 5700? I have cleaned the DVD and cannot figure out why the 5700 cant read it. Any help is appreciated. Thanks.
