What is the difference between these two? If I got a lens and used it for CIH does the VP50 allow more control over the stretch factors? Does the Duo simply do a 33% stretch and no in between? I suppose that would mean that movies between 1.78 and 2.35:1 (like 2.0:1 and 2.20:1 for example) couldn't be stretched with a Prismasonic doing a variable stretch, right? You'd have to watch as is with black bars in 16:9. Is this right?
