I was just thinking that it was probably also a deliberate choice to include the letterboxed GOUT with the full screen editions of the 2004 trilogy: If you were buying the full screen set it was probably because you didn’t like the black bars and/or still had a smaller tube TV on which to watch it, in which case the letterboxed GOUT Disc could only look even worse when compared to the clean, ultra sharp, pan and scanned '04 version… Another “See how much better the new SE version is” tactic.
Interestingly though when the original 2 disc E.T. DVD came out it had both the 2002 and 1982 cuts. However, like the 2006 SW DVDs, only the 2002 cut was Pan and Scan if you had the Full Screen edition. Fortunately the 1982 cut was anamorphic though! 😉
