Despite copying several hundred DVDs using DVD Shrink and DVD Decrypter, I am a newbie. I just did the same thing over and over because it worked - that is until a few weeks ago when Decrypter stopped working (Shrink works fine). I now get "Device Not Ready (Medium Not Present)." I read some old posts and took the following actions: 1) Tried to get new drivers. I could not find drivers for my old burner so I bought a new external one. Still got same error message. 2) I read a post where someone suggested changing the upper filters in "regedit." I think I followed that advice correctly (without understanding it) but no luck. 3) Changed media. That made no difference. I used many different DVD+R media before there was a problem and two different media since the error message and still get the same error message. 4) Switched to ImgBurn. I understand that Decrypter has evolved into ImgBurn, so I downloaded that. I get the exact same error message only I am little uncomfortable with ImgBurn having never seen that wonderful "Operation Successfully Completed" message using it. What's going on? Is this the best place to post this? Feel free to talk down to me. Computer technology is evolving far faster than I am. I have Microsoft XP if that helps anyone.
