but it looks like a Vedio shot
does the 60 and 120hz matters for a hdtv?

Regular TV (or the old style standard definition) consisted of 525 lines every 1/30th of a second. Problem was, all the odd numbered lines (1,3,5,7...) were drawn in the first 1/60th of a second, and then the even numbered lines were drawn in the next 1/60th of a second, so there was a complete frame only every 1.30th of a second. Someone got the idea that storing and displaying all 525 lines in 1/60th of a second, and then repeating it for the next 1/60th of a second, would somehow make it refresh faster and look smoother. It didn't. But those same people convinced themselves that it would also double the resolution since it drew the frames twice as fast. Again, it didn't.
Now comes HD tv, where a complete frame consists of 1080 lines, every 1/30th of a second, called 1080i. You still have the diehards who desperately want to believe that doubling the refresh rate will double the resolution, so Blu-Ray stores and displays a complete 1080-line frame in 1/60th of a second, and then repeats it for another 1/60th of a second, or what's called 1080p.
You cannot create what is not there. All the faster refresh rate does is show the inadequacies of the display. The same problem surfaced when CD's first came out. Analog music was stored on digital discs, and the superior rendering of the digital technology only served to accent the inadequacies of analog mastering. When mastering went digital, then CD's were a good medium to reproduce the music.
As Lois Lane will tell you about Superman, faster is not necessarily better. Video games are produced in 1080p and look good in 1080p, but TV and movies are produced in 1080i, and trying to display them in 1080p only shows the inadequacies of 1080i. If you want to watch movies, set your TV for 60 Hz.
