The current Mitsubishi and Samsung RP-DLP sets do 120hz, but that's not what I'm looking for... I'm looking for a feature comparable to SONY's MotionFlow or Samsung's AMP (Auto Motion Plus) found on their higher-end LCD models. My understanding is 120hz is a prerequisite for the set to be able to produce this effect, but not all 120hz televisions have this. It's one of the features that sets apart Samsung's 500 series LCDs from their 700+ series (cost difference is about $1000 for these sets). SONY's counterpart MotionFlow is being offered on most of their LCDs.
This is an effect that makes film look like video which I don't care for much, but it makes live HD video look absolutely stunning. SONY seems to insist on having it set to ON on their retail display units. You will certainly see it if you to a SONY Style store.
