So am I just SOL for changing the booktype with my disc drive?

[Lotus Gramarye]

Want to change the booktype of DVD+R to DVD-ROM, but even though I have an LG drive (I'm pretty sure; HL-DT-ST DVDRAM GTB0N) when I try to change the booktype with it I get the error "Invalid Command Code Operation."  From some googling it seems like this just means that my drive doesn't support this feature, but I want to make sure that's the case before I give up, since I'm not remotely knowledgeable on this sort of thing.

 

e: Nvm apparently I'm just an idiot.  Looking at the disc in Nero CD Speed w/e it does seem to have DVD-ROM as its booktype.  I guess I misread what ImgBurn was telling me.  Turns out my PS2 isn't reading the discs I'm burning cause the laser is fucked, not too surprising since it's over a decade old (though it still reads official game DVDs).
