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?

I've had too many issues burning DVD's on a mac, let alone a blu-ray. Unless it was a direct burn for an ISO, I had problems. I finally gave up on the Mac and just stick to my Windows 7 laptop for that kind of stuff.

The data disc idea for the PS3 will probably work as long as the file is encoded as a mp4 and has either AAC or AC3 audio tracks.
