The bonus material included in The Definitive Collection is something you won't get in the SE version. As for the audio and visual quality, it is as good as the laser disc copy, but some how for us who always look at digital DVD and listen to the DTS audio track, we may feel that the analog is not so up to expectation, and also the Dolby 2.0 and 5.1 audio track, just don't seem satisfactory. What can we do, the films was made during 1970's and 80's, that is the best they have during that time.
I myself just got one copy from www.endorforest.com, it's only $29.99 for a set, what big deal if George Lucas don't want to release them as he may think the small portion of us can't make him go richer.
