Thank you for the reply I also found additional information just incase someone has the same question like myself in the future.
Many people get confused by this, and the manufacturers don't help, they do this deliberately because it makes for good marketing. All signals are at 60Hz, whether it's from DirecTV or any other provider, or other sources such as Bluray. Newer LCD TVs have electronics that take the 60Hz signal and create a 120Hz or 240Hz signal from it. Since there's only 60Hz of data the 120/240Hz signal actually going to the display contains frames that have been created inside the TV (usually by "frame interpolation", which means taking two frames and trying to calculate the non-existent frame that would have been between them), and are not in the original signal. The theory is that by increasing the refresh rate, fast motion will be less blurry. But if motion blur comes from the source (for example in sports) then increasing the refresh rate will have no effect. Another problem with increasing the refresh rate is that movies originally filmed at 24fps (most film-based movies are 24fps) can look artificial and not the way the director originally intended. Going to 120/240Hz can introduce video artifacts (even headaches) in some cases that can only be removed by switching the enhancement circuitry off. FYI, the plasma manufacturers have joined the "refresh rate" war by quoting their own refresh rates, you'll see things like "480Hz subfield drive". It's meaningless, and can't be compared with the refresh rate on LCDs, because plasma is a phosphor-based technology not made up of individual pixels like LCD. There's lots of info about this on the web, although some of it gets confused by the same issues.
