To any Mac users having trouble burning the BDMV folders and getting it to play, burn it using Toast Titanium 10.
There is an option under the video tab for BDMV Folders.
Burn them that way and they will play fine on PS3 & BluRay players.

I just heard about these a few days back and watched the whole Trilogy this weekend. Damn beautiful work, man.
The asinine changes to the official Blu-Ray set, plus the lackluster effort to the new deleted scenes on the official Blu-Ray had me seriously doubting whether to shell out the $100 for it. Watching these over the weekend re-enforced my decision not to buy them.
Never thought I'd see the originals in this level of quality again.
