Ok, the TB broadcast of ANH is in better shape than TESB, missing only 6 frames (assuming "Star Wars" title card at frame 711):

50193 - close-up on Luke listening after Ben says "...it binds the galaxy together." May not be exactly this frame as its difficult to tell but certainly a frame is missing from this shot. Middle of reel 2.

85223-85225 - last 2 frames of Alderaan exploding, plus first frame of Luke training with his lightsaber on the Falcon. Towards the end of reel 3 (reel 4 begins at 90295).

147671+147672 - last frame of the astromech being lowered into the X-Wing with the mechanic waving his arms, first frame of next shot looking down on an X-Wing. Reel change.

Thats it. I'm surprised there weren't more frames missing around the reel changes, and am even more surprised there were so many missing mid-reel. I wonder if there were ad-breaks in the original broadcast that could be responsible for some of these? I know that the Reivax broadcast is missing 15 sequential frames during the Ben/Vader duel alone!

I hope this is useful. I've been keeping an eye on your release thread at the work you're doing, and downloaded DJ's samples and both are looking exceptional considering your sources! I'm looking forward to checking them out once they're done!
