Plus the "Gathering", to date, is the only episode/movie to be presented in its original 4:3 format.
Is this 2004 dvd version an open-matte or cropped version of the original 4:3 picture format?
My copy is in a 16:9 widescreen ratio.
You sure you aren't watching it on a widescreen TV that's stretching the 4:3 image (or even zoomed in to create a 16:9 image)? Since as far as I can tell it's only been formatted for 4:3. (And the earlier 2001 DVD release of "The Gathering/In The Beginning" had the "Gathering" in 4:3 while "In The Beginning" was in anamorphic 16:9.)
