Gave the THX DVD's a quick look last night to examine the fullscreen versions and see if they are truly open matte or not. Goldfinger is partly rotted! I can't get the fullscreen layer to play at all. The menu partially loads when you select fullscreen, and then the player chokes on it. Widescreen layer is unaffected. Dr. No and FRWL are both intact. (I watched all three synced up to the Criterion MP3's a couple months back.)
A quick glance at FRWL reveals more info top and bottom, but some image loss at the sides.
