if you use nero to burn (stolen from another board) this is what I did
Open NERO Burning ROM. From the main screen, there should be a drop down menu that shows your DVD Drive. Mine says E:_NEC DVD_RW ND-3520A. I can click the dropdown and also select my CD Burner. To the right of that dropdown menu, there should be an icon that looks like a tiny computer with a cd drive sticking out. Click on that icon.
It should take you to a menu called "Choose Recorder". It should list your burners. Mine says
Image Recorder
TDK CDRW4800B
NEC DVD RW ND-3520A
It will list the status of all of them, et et. Make sure your dvd drive is highlighted. In the bottom left, click the options button. Once you click that, it will have a box for buffer underrun with a check mark, and then another dropdown menu that says
Book Type Settings.
Mine is selected to DVD ROM, but there are settings for Automatic, Physical Disc Type, or Current Recorder setting. Theoretically, if you flashed your drive with firmware to enable bittsetting, you should be able to leave it as current burner setting, but select DVD-ROM.
After youve selected the Book Type Setting to DVD-ROM, burn a disc. After it is done, leave it in the drive, then go to the "recorder" menu heading at the top of the tool bar, select disc info, and click on it. It should tell you what book type the disc is. If you set it up properly, it will either just say DVD-ROM, or it will say R+ (Booktype set to DVD-ROM)
