Maddog Firmware

I purchased the following external USB 2.0 drive:

MD-18XTFE
TSSTCompCD/DVDW SH-S182D
(Samsung?)
18X DVD+R 12X DVD RAM 8X DVDRW 8X DVD+R DL 16X DVD Rom
MegaSTOR 18X Triple Format External DVD-RW
USB 2.0

I am using what I believe is the latest firmware from Samsung since nothing is listed on the MD site for this drive.

Querstion: Does any know of a modified software for this drive that will allow permanent bitsetting? Curently I have to use Nero CD Speed to change to DVD-ROM for each disk I burn. It would seem there must be some way to do it on a permanent basis. E-mails to MD resulted in no help - they said it should be done automatically but it does not.

Thanks in advance for your help.
