Answer 1

Your friends, most likely, aren't using an HD signal. SD on an HDTV does not look good. This is because the HDTV must invent a large number of pixels to fill-up the screen.

For example, in order to display a 480 SD picture on a 1080P set, the TV's processors must add 600 lines of picture.

Doing this degrades the picture.
