After one DVD movie was run several dozen times, the player would no longer

John, I did buy a cleaning disc, used it, and still the indicated DVD would not read/play - while others would. However, a little bit later, after my son played another movie, he tried the rejected DVD again - and the player is now "reading" and playing the DVD. Suspect there's a bit of "memory" and unknown program element that - at first, anyway - will continue to "remember" and reject a given disc. Should note that the DVD, "Sister Act I," had some food-finger prints on its playing surface - likely triggering the "memory/response" undisclosed programming with the player. And then, after cleaning, that first attempt at playing the then-cleaned CD was again rejected; but, later, it was accepted. Theory, at least.

Thanks for the follow up, fingerprints will play a roll in playback performance. Thanks for the follow up, fingerprints will play a roll in playback performance.
