812s@832s or 812s@700a and Video-DVD

Hi All.

812s@832s or 812s@700a with any firmware doesn’t read Dvd video (may be only SL) disks. It recognize it as DVD+RW with code: RICONJPN W01.
Nero CD-DVD Speed show error message “INVALID FIELD IN CDB (052400)”

How solve this problem?

Best regards

The disc media code shows fine when at a regular 812S?
