Mine also has a similar problem. After recording something, when you press stop, the postformat takes ages and then the message disc error comes up. The menu doesnt appear and the disc is useless. The same goes if you use a previously recorded disk that works until you add something to the recording, rendering that disc useless as well.
Ive cleaned the lens, tried 4 different makes of disc, and done a hard reset but all with no joy.
So i would be really grateful if anyone could know the answer. Thanks
