Re: blobs and matte boxes--Harmy, I thought you said that the contrast in the original theatres should have been properly adjusted so that they wouldn't have been visible to the audience, and consequently, having them appear would not fit to the actual intent of the project.

Some matte boxes are more visible than others, depending on the brightness of the background (there's one against a Star Destroyer in ESB that's pretty front-and-center). It's a matter of degree--most of the matte boxes may have been barely visible in the theatres if you looked for them, rather than jumping out at you like they do on the home video releases. Having them be as obvious as the home video releases would certainly not fit the intent of the project, but so would erasing them altogether. But there's a few pretty obvious ones that were likely always pretty obvious.
