What a difference 10Hz makes.

[ppppenguin]

I went to America a few months ago & all TV's I saw were plasma or LCD so noticed no difference...

You wouldn't see a difference with LCD screens because they inherently have no large area flicker (Zero order hold function - the cells retain their previous state until switched again). Plasma screens will have large area flicker unless frame rate multiplication is used, and that's unlikely for what is now an old technology.
