As for motionflow and the seemingly 60 fps that you see - it's basically a technique known at frame interpolation, whereby 3 artificially created frames are filled between each successive frame of the original 60Hz input signal, in order to boost the output signal to 240Hz. This effectively bumps up the motion resolution to 1080, so picture detail is never lost even during the fastest moving scenes in film and game content. With motionflow off, the motion resolution is 300 vertical lines i.e. 300p, so having it on makes a significant difference.
Initially, Sony TVs came with only 2 motionflow settings - standard and smooth. Both did their job fine, but the end result wasn't as pleasing. The effect resulted in video content looking too artificial or something that was shot from a home video camera. With the advent of their newer line of TVs, Sony has introduced the 'Clear' setting, which has effectively eliminated this issue.
