No, the point of bitsetting is to fool your player into thinking it's playing back a pressed commercial dvd instead of a DVD+r or +rw.
I just made this post on another forum:
Bitsetting allows you to change the "book type" of a burned DVD+R and sometimes DVD+RW (if supported). If you don't change your bitsetting, your DVD player will check the "book type" of the burned disc. If the player doesn't support DVD+R (or +RW) by default, it may not play. However, if Bitsetting is set to ON with your burner, your burned disc will not be identified as +R or +RW, but instead as DVD-ROM. DVD-ROM is what pressed (commercial dvds) are set as. Since all commercial dvd players are designed to play DVD-ROM discs (and not necessarily +R or +RW) , the compatibility of your burned discs will increase. But that's no guarantee it WILL play.
For example, I've heard some xbox game consoles won't play DVD+R, but if you burned it as DVD+ROM, they will work.
My suggestion is first try a DVD+R bitset to DVD-ROM. If you don't know how I suggest poking around the forums here:

It may be necessary to upgrade your firmware, as i did with my plextor dvdr
