I have an external DVD writer which supports DVD+/-RW. It has been set up and is recognised by SuSE when hotplugged, but when I try to write to a DVD+RW using cdrecord-ProDVD it fails. Is the problem one of compatibility between the DVD writer and DVD or is it with the command? Any help much appreciated.

The command I use is:

> cdrecord-wrapper.sh dev=/dev/sg1 -dao /home/alastair/Downloads/debian/sarge-i386-1.iso

(NB: cdrecord-wrapper.sh simply calls cdrecord-ProDVD but with a license key)

The error is:

Sense Key: 0x5 Illegal Request, Segment 0
Sense Code: 0x30 Qual 0x05 (cannot write medium - incompatible format) Fru 0x0
