This appears to be for Disc 2 of the 2006 Event Horizion Special Collector's Edition DVDs, which one of the bonus features contains 5 Documentaries entitled The Making of Event Horizon.
They are:
Into The Jaws Of Darkness, The Body Of The Beast, Liberate Tuteme Ex Inernis, The Scale To Hell, The Womb Of Fear.
Though delayed a while from the movies original release date and DVD, it is still an insightful look into some of the background and history to this wonderful Science Fiction horror movie. Any true fan will already have bought themselves a copy, which also comes with the original "enhanced" version of the movie on Disc 1 with a commentary track by Paul W.S. Anderson and Jeremy Bell, as well as some more bonus features on Disc 2. Included on Disc 2 will be some missing scenes, unfilmed scenes, conceptual art, the filming of, trailers and more interesting stuff.
It is however not a Directors Cut, nor just the original theatrical version, nor a Sci-Fi Channel or HBO special of the Making of EH.
