Something occured to me as I was looking over the new Indy box set (I'm promised it for Christmas, so I can't buy it yet....aaaaargh). As far as I know, these are the first DVD's from Paramount since Titanic to be THX digitally mastered. In the heyday of Laserdisc, the THX logo was on almost every release worth owning, but since DVD become popular, only Fox and Buena Vista/Touchstone/Disney have been using it regularly. Even releases from Steven Spielburg, like Jurassic Park and ET (which were THX on laserdisc and VHS) have not carried the THX logo. I know THX had some issues in the early days of DVD (such as signing off on non-anamorphic, non-hi def laserdisc transfers for use on DVD) but they have had their act together for a few years now and I wonder why the studios they used to work so closely with no longer seek their help. Universal in particular could definately benefit from some outside help in the quality control department, so they don't have to keep replacing defective pressings. Also, is their any difference between discs that are "THX Digitally Mastered" (Star Wars I and II, Indy) and discs that are simply THX certified (Signs, Who Framed Roger Rabbit)? Does THX actually do the mastering in-house, or do they just send people to oversee the process at the respective studios? Just curious, I'd love to hear from anybody who knows.
