you should capture those pre thx silver screen laserdiscs which are in widescreen. Why? well for one thing nobody else on these boards has of yet. that could be another little project even though you are gonna use somebody else release as a videotrack.
The other two trilogy sets I'd like to see captured are the spainish set and the 1994 pre faces coffret collector french set.
I would settle for screen caps of all of these as well to judge the quality.
