The actual amount of crop was somewhat dependent on the specific installation. But you are correct, I should have said that the combined ABC prints' AR was ~ 2.85:1. I do crop the sides a bit in my HT to fit my 2.65:1 screen.
No, the 35mm print certainly wasn't P&S, they just cut off the sides. And it looked like crap as well. 2.85:1 was the intended projection aspect ratio.
