I actually plan to release a DVD9 AVCHD and then also a 15 or so GB mkv. I was even thinking about a BD25 release but since I don't have a BD burner, I don't think I'll do that.

A 1080p mkv in the 15-20GB range would be fantastic! With multiAVCHD, I could combine the movie with the 2.6GB "Making of Star Wars" from the Blu-ray set, together with a simple main menu.

This could actually be done with all three of the movies -- each with their respective classic documentaries. And they'd all fit comfortably on a BD25. I love it!
