So I got a new tv, a 42" Vizio LED HDTV flat screen.

The tv was stunning on display but now that I have it all hooked up some channels look blurry at times. Now I am using Digital cable but not High Definition. I was using a normal big boxy colour tube tv before and every channel looked clear so is this the effect of not having HDTV? Is my tv so advanced that without high definition some channels are going to look kind of grainy and weird? BTW this tv was the display model so I know that it looked awesome on the floor there but it was probably showing in high definition.
