XBOX360 backups - do I need to do anthing special?

Optiarc 7173A (firmware 1-02)

Burns OK but wont play. Using Verbatim DL.

Previously had a Sony burner and this worked fine.

Do I need to do anything special (i.e. update the firmware) for this drive to produce workable XBOX360 copies?

Using Liggys AD-7173A Bitsetting firmware 1-04

Create new backups first.
