P.S. Nobody thought to try 7-Zip? It's freeware. It works. I said so like an hour ago.
I saw your helpful posting, but I'm not so anxious to try 11j that I'm rushing out to get YAZP (Yet Another Zip Program). Obviously, Jim needs to fix the .zip file - and perhaps tell us what (if anything) changed between 11i and 11j, in addition to the frame rate stuff.
We don't need to be spending time trying to test stuff that hasn't changed. That's a waste of our time, and Jim's time.
