I'm in Europe and have only just come across this, but maybe in the states you have had it for a while.
It is a feature on alot of new Samsung HDTVs called 100hz motion plus. It strips films and tv shows of most of their motion blur... making a classic 35mm film look like a bad soap opera. Worst of all, it is a default setting.
Has anyone else seen this in action? It is awful and hopefully not a trend that willl stay.
