i remember let the wookie win being cut for time during this broadcast as well as some lines from threepio in the desert before captured by the jawas, and sold to uncle owen and luke.
I do not think the edits had anything to do with offensive dialogue or scenes but more to do with allowing space for advertisements. The average viewer probalbly would not have noticed.
I find this to be odd because I have on tape a television station edit of the undiscovered country star trek 6 that does similar trims.
