They're sparse at best. There is a greater reason to have them on the DL version than the SL version, but nonetheless, menus do help with compliance on older models. For the SL version that's been torrented, it really just allows selection of the two subtitle streams. There is no motion and audio in the menus. Especially for the SL, I thought it best to reserve all possible space for the video stream.

The DL version does have more features. 5.1, 2.0 and the commentary.

If ever I finish ANH there will be several more things. Alternate subtitles that make Jabba's scene less redundant and more effective. And perhaps a big fat easter egg that'll be fun for years to come.
