if one of its uses will be to compare edits i think you should add in some info on the movie format/specs
ie, how is it available (SL-DVD, DL-DVD, avi, mpg, etc) this should obviously be the release format only because anyone could take an avi and put it to a dvd or vice versa, but it's nice to know how the author originally released it.
also, information on if its PAL or NTSC, Aspect ratio information (Anamorphic/Letterbox/4:3)
if there is official disc/case art available
what extras are available on the discs
running time
im sure there are more, basically im just thinking the kinds of basic questions people ask about the edits/preservations when trying to decide which one they should get
