I could be wrong, but I think setting the Book-Type (Bit-Setting) to DVD-ROM is a function of the burning software. I usually use DVD Decrypter to burn Iso's and haven't had any problems with compatibility. Burning coasters is another problem though. Use good Media, keep the Burner's Firmware up to date, burn at a slower speed.

CDFreaks is a pretty good site for info about this type of stuff.
