This confusion (Ewok Adventure vs. Caravan of Courage) stems from the fact that there were two versions of this film. Almost identical, the only difference was the opening credits. The original TV version said "The Ewok Adventure" in the credits, and the European theatrical version said "Caravan of Courage." When the recent DVD was released, for some reason they decided to use the "Caravan of Courage" credits, in full screen ratio.

Please correct me if I'm wrong, but I think this is the case. The old "Ewok Adventure" credits can be found on old VHS tapes and LD's.
