i have strived to learn how to do this and now i can tell you. one way to do this, is a displacement map, i made an animation using some photos from this site http://www.karlklomp.nl/mda/still.html of those real glitches, then you put the animation in your comp, use it as a displacement map and ta da you've got some messed up footage.
another way (something that i did) is to create animated elements that you can lay ontop of the footage and set to a transfer mode to imitate some things, i've got one that makes some purpleish distortion like recording on the lead of a DV tape, another that is some random bars of noise and scan lines, and a few others, all built using fractal noise, and a few other effects ontop of it.
another good trick is to capture some footage from an OLD VCR into the computer, but you probably have to go analog, right up to the capture, or you'll just get a blue screen.
if there's anyway i can send you the pre sets, i will.
EDIT: here's a pic of one of the pre sets i made to look like part of the "cloverfield" logo in the trailer.

thanks a ton! the displacement map technique actually worked better than i expected. but if you could send me those presets that would be great! thanks!
