OK. . . Now I'm stumped I just copied my first couple of DVDs using DVD Decrypter and Shrink. The copies turned out beautiful thanks to bbmayo step by step instructions and played great on my stand-alone DVD player. Now for the problem. When I try to play a purchased DVD my player doesn't recognize that there is a disk in the player. It says no disk and tells me to insert a disk. I never had this problem until I played a disk that I just burned. I can play the burned disk with no problem but the player will no longer play a store bought disk. This is wierd. If I let the player sit overnite and in the morning insert one of our store bought DVD movies it will then play. I then insert a burned DVD and it will also play. I then insert the purchased DVD again and it will not play unless I leave the player alone for a while. This is driving me crazy! Has anyone ever heard of this problem before or know how to correct it? The player is a Sony DVP-NS300.
