I was unable to play a particular disk in my player. The motor or something just made a fairly loud whirring sound. So, I removed the disk and confirmed that my player is OK by trying 2 different disks. I tried the apparently faulty disk in another player and it seemed to be fine. Now I have a replacement disk with the same movie and again my player just makes the same ugly sound. BUT, when I put this one in my back up player it makes a few sounds and then smooths out BUT never plays. My back up player is a laptop PC and it shows no files on the disk. Any ideas?? I will try a 3rd disk but I will be surprised if it is any different.
