How do I get this specific distortion?

[enzyme]

How do achieve this effect. I want to create tv distortion, but not in the form of noise. Like when things get stretched, distorted, and look all jagged horizontally. Very similar to when you are losing a video signal.

I have a perfect example, but I can not post it because I am brand new here.

Okay here is the perfect example of the effect I am looking for. Can anybody help?

That is precisely the kind of thing I need to do also.
