NEC 5170A copying problem

[qanda]This thread is about the Optiarc AD-5170A. Click here to see full specs[/qanda]hello everyone, my 5170A burner writes fine but it very rarely reads and copies the disc it wrote 30 seconds ago to the harddisk. I can’t watch a movie I just burnt. When I try to copy them to the harddisk i get cycle reduncacy check and when i try to watch them it freezes the computer unless i open the drive. It also happens with my old discs written with it. But my standalone divx player reads them flawlessly. Please help :frowning:
