alright to see if your burner will support bitsetting check here:

where it says in the 4th column "bitsetting" as long as its not looking like its crossed out like some of the others then its supports bitsetting. I dont know that also means it supports booktype
bitsetting...DVD Players read the first 4 - 7 bits of whats on a DVD-ROM/-r/rw +r/rw to determine what type of media is actually inserted to determine if its a supported type of media that it can play. Bitset of "0" means the media is a DVD-ROM and most dvd players should recognize this and play it even if its a changed DVD+R media that has the bitset from "X" to "0" or the booktype changed from DVD-XX to DVD-ROM.
You can change the booktype of a changed media from DVD-ROM back to what it was, but I dont think you can change a real dvd-rom to a recordable media
