This isn't ISO News. You're playing with the big boys now. I couldn't care less if you screw up your own movies. It's when you start passing out faulty advice that I object. i've tried many times with ntsc 29.970 interlaced movies to use ivtc and they sucked Of course they sucked. They haven't been telecined in the first place, and therefore can't be IVTC'd. And what is Force Film but a "weak" form of IVTC? And you're recommending it for video sources?
