BR should be pretty easy. For the US theatrical simply remove the additional bits from the Criterion International PCM, and insert them into the Director's Cut PCM to reestablish Dolby Surround PCM for both the US 1982 and a customized DC.

I too agree that the DC with reinserted violent bits is best overall in feeling with the 1982 release before going to the fully spiffed up and blue/teal Final Cut.

BTW, how do you guys go about your LD audio captures? Here's my query thread in how-to's: http://originaltrilogy.com/forum/topic.cfm/Simple-and-cheap-capture-method-for-LD-with-bit-perfect-digital-audio-on-PC/topic/16892/
