My theory is that Pacific Titles did what they said: they went back to A and B and did a new C. There would be no point in saying Pacific Titles re-did the transitions using new optical printers if they didn't do this. What I am saying is that ILM then slapped new digital wipes over top of the new 1997 opticals. Why? Dunno. Smoother looking? Hide some splices? No idea. Why did they speed up the opening logo? No idea either. But they did.
I don't believe that Pacific Titles just bullshitted all that.
The only other explanation is that ILM re-did the work that Pacific Titles did by going back to A and B themselves and making yet another C. But this doesn't explain why the wipes are exactly positioned to hide the 1997 ones. The only explanation that accounts for this is mine above. So thats what I'm going with for the moment.
