I just finished doing exactly this using the blurays. Only issue aside from special edition changes is some scenes and colors not being exact representations of the theatrical releases of any of the films is the end sequence from Last a Crusade. The credits begin to roll before the shot on the demo is set to end. I working that out now. I'll do another edit using Harmy's despecialized footage. So far I have the 5.1 mix from the DVD release and I'm capturing the two channel from my laserdisc. Honestly though, even with the special edition shots, it's really a great home theater demo.

glad im not alone :)
