Apparently my Mac is too old to be able to access iTunes Extras. I guess the technical hurdles are too great for my machine to stream 480p "Legacy content." I heard from someone who did buy that the Legacy content is just the same SD video as the DVDs.

Sh*t..... that means that the deleted scenes are also highly likely to be the SD versions from the DVDs as well. :/

It's like Lucasfilms knows we're just chomping at the bit for HD versions of the deleted scenes so we can make better fanedits of the movies, so they're intentionally screwing with us, lol.
