I/O Magic IDC1168DL and 1.03 update

Went to Staples this AM and got a I/O Magic burner for $20 AR. Found it was a Benq DW1670. Was burning my 4X DVD+RW at a 2.4 Speed. Found out the firmware was 1.00. Tried to update it to 1.03 and got the msg “Not allowed to upgrade”. Found the MCSE program and now running as Benq DVD DCDW1670 and burning at the correct speed. Any other enhancements with 1.03?
