Difference between 60hz and 120hz?

Better get a tv that supports 24p or 24hz updates.
If you use 120hz motion flow only 1 out of 5 frames you see is from the actual movie. The rest is all interpolated, smoothed out from the motion blur present in the source material. A tv that supports 24p will display the movie as was intended. TVs that support that can also reverse 3:2 pull down back to 24fps, useful for watching dvds.

Most HDTVs already do and have for years. 

The 1080p 60Hz HDTV I bought back in 2007 plays BD, DVD, etc. at 24fps.
