Apologies to be dragging up such an old thread, but the lack of support for iTunes Extras and LP is really disappointing. Given that the Apple TV 2 can now mirror the screen of a connected iPad 2, and that there is no functional difference between iTunes Extras/LP and a web page displayed in Safari using many of the webkit CSS stylings, (or, indeed, the very transitions and translations that are used to create the Apple TV 2 menus themselves)there should be no barrier to iTunes Extras appearing on the ATV2. The problem, I think, would exist in that many of the multimedia files used to create the extras content would not have an Apple Library ID, as they exist outside of regular content. With no library ID, on a device that is designed primarily to stream and that's it, accessing these files becomes a bit more challenging.
Personally I think Apple should develop a "hidden" classification for their media files to sit alongside "Song", "Movie", "TV Episode", etc, which will allow a file to be accessible by iTunes, but not appear to the normal user in their library file listings. And while I think the entertainment industry has gone over-board with DRM, such an approach would allow studios some degree of protection for their "extra" content. At present, with the files sitting outside of iTunes' regaular managemnet procedures, there is no digital protection on these at all. This lack of copy protection is one of the reasons (in my opinion at least) that the format has not seen greater embrace by the industry - there is simply no copy protection on any of the special features, so what is provided usually is of low quality, and low interest. So usually I am left purchasing the DVDs, purchasing the iTunes movie, and then copying those special features into iTunes and developing/adapting the menus through which to reach them. Which can be tedious. VERY tedious!
