Go to the section titled, "Puttin' on the Hz." It should explain the artifacts you are seeing.

Alright I read that, thanks. So I guess "Motion Enhancement" is the 120hz feature itself, I was never certain of that and thought it was maybe just an additional feature.

I just don't understand why the tv has this small video glitch when I have watched movies on other LCDs without the 120hz technology and have never seen and blur or anything before.

No it isn't. The article isn't completely clear but they aren't the same. They're kind of apples and oranges really.

120Hz is the refresh rate. The higher the better, generally. 120 is particular is nice because 24, 30 or 60 frames per second video can be shown without any frames "left over" or lost because 120 is a multiple of all of them (24x5, 30x4, 60x2). Showing 24fps on a 60 Hz TV can create problems with the video quality, but on a 120 Hz TV it should look perfect.

Motion enhancement is a feature on the TV that you can turn on or off. It doesn't affect if the TV is running at 120Hz or not...that doesn't ever change, a 120Hz TV runs at 120Hz. What motion enhancment (and similar gimmicks like "motion flow" etc.) changes is how the video signal is processed to show on the 120Hz screen.

Turn it off and it does nothing and you see the original video signal as it was sent. Turn it on and it does a bunch of interpolating to the signal to try to turn it into something smoother and sort of 3D looking.

Basically 120Hz lets you do motion enhancement, but you can have 120Hz without motion enhancement.
