The 6-disc set (which streets on 9/17) will include all 24 first season episodes, along with video of Kiefer Sutherland introducing Season One and teasing Season Two, and an alternate ending to the season's final episode with optional audio commentary. Video is anamorphic widescreen. Audio is English Dolby Surround, with Spanish and English subtitles.

By the way, the press release Fox is sending out today says full frame 1.33:1, but I have CONFIRMED officially with the studio this afternoon that the release is incorrect - the discs are indeed anamorphic widescreen. Just FYI.
