I don't know much about the american releases, I have seen a few of them and all they did is that they resized and cropped the videos to HD dimensions + did some awful contrast/lighting/colour correction + censored some scenes. The best release so far is the Japanese Dragon Box in 4:3 standard dimensions with a really really bad audio quality.
I remembered wrongly about the 16mm prints.
These are the two "Level sets":

They were frame-by-frame restored from the 16mm masters. It truly sucks that they stopped producing them.
With that being said, let's move this discussion to here: http://originaltrilogy.com/forum/topic.cfm/Dragon-Ball-Best-of-Breed-hybridmaybe/topic/15938/
