I really must be "blind". I can see the difference side-by-side (especially the moving ball) but the difference is so slight. Even 15fps looked fine to me. If you showed them to me back-to-back, I don't think I could tell the difference. Which is frustrating to me, because I know the difference but I wish I could see the difference. I feel like my eyes are failing me. This is watching the downloaded avi.
