So the version here on youtube is a 16:9 widescreen crop of a 4:3 TV crop of the original 16:9 filming? And the remaining CGI are only the 4:3 crop from the lost 16:9 originals? Did I understand corectly?

Then, is there a version somewhere with original uncropped 16:9 live action and 4:3 CGI? I can tolerate side bars. To me, seeing the complete video frame is more important than a consistent frame format.
