I've never had this happen before. My daughter was watching a brand new DVD on a Sony 5-disc player. This message came up. Just prior, I noticed the disc was changing colors. I plugged the video cable in securely and thought it was fixed. A bit later it stopped with the "disc is dirty" message. Brand new DVD. I looked at it closely. Perfect. Could it be I need one of those lens cleaner discs? I'm very careful with my discs and player, so this is extremely annoying. I looked on the net and it seems like others has the problem. C:13:00 The Disc is Dirty" error message.
