Liteon 451S which is the best firmware for this burner?

CG5J: http://codeguys.rpc1.org/firmwares/dvdrw/832S.CG5J.patched-cf.rar

This firmware doesn’t work, because my dvd burner is a DDW 451S, from one Ilo home dvd burner.

CG5J: http://codeguys.rpc1.org/firmwares/dvdrw/832S.CG5J.patched-cf.rar is for LDW version.

Please moderators, delete this thread, i put a new tread with more information about the problem, thanks in advance.
