If possible, I suggest not doing transfers from NTSC-PAL and vice versa. I use DVD studio pro (on Mac) and version 1.5 can combine both NTSC and PAL clips in the same project (Versions 2 and 3 can't do that for some reason). Of course TV capable of reproducing both systems would be needed.

Regarding AFI documentaries... There is no reference of one for Ridley Scott being made. The one with Cameron did feature some aliens EPK footage, but all of it in its entirety was released on The Alien saga DVD

AVP was pretty decent considering low budget and lack of involvement from RS & JC. In a recent interview even Cameron himself placed it as 3rd best alien movie ever (probably after Alien & Aliens. He hated Alien 3... I wonder if he got to watch the new cut, which improves it significantelly making it look more like Fincher we got to know)

Alien War had great props. One Colonial Marine told me they had exact replicas for Pulse rifles but they were falling apart due to wear and tear, so they had to replace them with more robust models. Does anyone have any footage on Alien war? Even smaller size featurettes taken off internet might look decent full screen, at least as an easter egg. Speaking of attractions, there is a small segment on Alien in a "film history" tram tour in MGM Disney studios in Florida. Just animatronic of Ripley and Alien jumping off the roof...

Has anyone seen any vintage TV appearances done during promotion of Alien & Aliens? I'd love to get hold of those...
