Release Notes
-------------------------------------------------------------------------------
I am not aware of any other CED transfers out there, so here you go. This is
really only of interest to the hardcore fans and is more of a curiosity than
anything else.

The 1982 CED features the same version of Star Wars as the 1982 and 1983
laserdiscs. These discs all feature a different pan and scan transfer than all
other home video releases. Other than that, there's nothing extraordinary about
it. That's why I chose Xvid instead of DVD.

There are a few places where the video jumps around and there's some scratches
here and there. Nothing I could do about that.
