"I had the same problem it turned out to be an incompatible/faulty disc removing the disc from the drive cured the fault"
"Strange thing is it the disc works fine on my pc and ordinary pana dvd player put it in the recorder ...u99 every time. I had to take it apart and put it in 5 times just to make sure ...heavy jpg content maybe ? Strange but true ?"
Hope this simple answer is the cure.
