You can only use bitsetting on +R/RW media.

It's a way of making a +R/RW disc look like a DVD-ROM so that older
players will be able to play it.

For a DVD player or drive to identify what kind of disc is loaded, it
queries the so called "Book Type Field" found in the lead-in section
of each DVD disc. These few bits, commonly referred to as
"compatibility bitsettings" tell the drive which low-level format
specification does the media conform to, such as DVD-ROM, DVD+R or
DVD+RW.

Most DVD players will read a DVD+RW or DVD+R disc without any
problems, however a small minority of them report a disc error when a
disc is loaded that is not marked as a "DVD-ROM" disc in the
compatibility bits. Ususally, these players are physically able to
read the disc (since DVD+RW reflectivity is identical to that of a
dual layered DVD-Video disc, which all players must be capable of
reading), but their compatibility problems are due to different
interpretations of these bits in the various firmware versions. In
most cases, the problem can be solved by updating the firmware.
