Once the 1st step (reading the DVD) of DVD XPRESS is nearing completion, I get a message that says "Error reading sectors." Then afterwards there's another message that reads "Unable to Read DVD," even though it practically read 100% of it. Can anyone tell me what's going on? It just started doing this. Before this problem, it would read the DVD's fine. Then when it was burning (2nd step), it would stop and say "Disc Writing Error." Please help . . .
