I bougth a Toshiba SD-R5002 and installed it into my computer. It is jumpered as a slave on the second EIDE-Channel (Master is a Liteon DVD-ROM). I can access the Toshiba in certain ways: i can play DVD-Movies with WinDVD, some Information-Functions inside different Buring.Tools report the name, also the format and capacity of a new DVD inside.

But i cannot burn anything on the DVD. I have tried:

ULEAD DVD MovieFactory SE: Error "cannot burn data on disk"
NERO 5.5.10: System hangs
VOB Instant Write: System hangs

And "system hangs" means: no Ctrl-Alt-Del, no Reboot-Button, only Power off is possible.

Any Ideas ??? Thank you very much.

P.S. I tested it with different DVD-R, DVD-RW.
