Would be interesting to see key sequences would look like in smilebox.
I was pondering a preservation of the Criterion extras, and other bits from the later LD's that never got ported over. (The Arthur C. Clarke lecture did make it onto the early non anamorphic DVD release, IIRC.) I own nearly all of the editions mentioned.
The extensive Criterion CAV text and still galleries pose a problem in how to properly present them on a non LD format.
