I have a Sony DRU-150A DVD +/-R.. I'm using NEro 6 and I'm getting a KEY_MEDIUM_ERROR.. I know everyone will say to try a different program, but I've done that and none work - each giving me a different message and problem. I can burn CDs and DATA dvds but no movie dvds. I made the video with DVD Shrink tried both the video_ts folder transfer and ISO file and none work and both give me the same message. Any ideas? I've been losing my mind for a week trying to solve this. Media used: Starlogic (Princo) and verbatim.
