Thanks, but alas, I'm on a Mac. With the ISO's it was easy b/c I can automatically mount and burn a disc from those. With ROTJ, I found this app "Burn" which seemed to be the right thing, but I guess not. (And BTW, the movie plays fine on the Mac itself--I'm just having issues getting it on a playable disc for PS3.)
Anyone burned a straight BDMV on a Mac?
