Im sort of an E.T. expert as ive seen it millions of times since I was a kid, its been a while since I watched the 20th anniversary but as far as I know all the changes are listed on movie censorship, the 20th anniversary has a new digitally remastered soundtrack the only 2 entirely new scenes are E.T. taking a bath and Gertie and Michael being picked up on Halloween night by their mother most of the alterations are enhancements to the E.T. animatronic giving him more dynamic facial expressions, basically just about every shot of E.T. is replaced with a cgi model sometimes entirely and sometimes just parts, the only actual altered bit of the audio track is the line between Michael and his mother concerning his Halloween costume instead of her saying terrorist its replaced by hippie but the whole exchange is way shorter than the original line, their are altered shots such as the bike passing the moon (Elliot has his cape now)
actually a lot of shots are entirely replaced and really can’t just be rotoscoped into the blu ray footage id say a 720p blu ray rip mixed with the 720p hdtv rip of the 20th anniversary would be the best splice in any new shots and scenes, then just sync the dts soundtrack and the dolby soundtrack for good measure and ta da

the 2002 2 disc special edition dvd has the DTS 5.1 track along with the Dolby Digital 5.1 track im not sure about the single disc releases, though id assume it does
yes I started this thread and sort of seem like I need to put my input in and I think no matter how people feel about the walkie talkies, they should be included along with every new shot, its meant to be a preservation a HD version of the 20th anniversary 100%
found the opening logo on youtube in 720p I assume the hd rip includes this however
