Just to keep you guise updated on the info I've found. It's not much, but perhaps it would be a good idea to contac this network also?

After reading a few articles on the net, I understand that this network, (just like WGBH), has also described two star wars films, which aired on TV. I could find no info about which of the films it concirnt, but according to the article they should have been described by joel snyder.
I'll try e-mailing them soon to see what they can tell me.
Kind regards from allan
