"Disc With Unsupported Format in Drive..."

[B_L_Z_Budz]

Hi people, help me with this strange problem PLEASE. I backed-up a movie via DVD Shrink and Roxio Easy CD + DVD Creator 6 to a DVD+R. After burning it, I watched it on my DVD drive and it worked great. That was yesterday. Today, I put the same disc into the same drive and try to play but get the message, "Disc With Unsupported Format in Drive" and for the life of me I can't make head or tails of it. What gives?

Try cleaning the disc...

The disc looks fine to me (w/ the nekkid eye) but I'll give it a cleaning and cross my fingers. Thanks.
