Q: How do i move a video,say,from iTunes to my iPod?

Oh, no i think i clicked Solved but it's not at all solved and i don'tt see a way to reverse it and clicked unsolved.

I'v tried reading the Manuals but still don't see the solution. 

I think I've misworded my question.  Perhaps i shall have to start a new question.

What i want to know is very basic.

How do i take a video i see on either youTube or another side and put it either on my iPod (i guess via iTunes) or put it into a document or an email??

Do i copy some link?  Copy what exactly?  Do i click and drag something?

I think if i knew how to get a video to iTunes I could be able to sync it. 

But i don't know the first thing, how to get a video onto iTunes, or email, or a document.

Thank you both.

The FAQs you suggested do not seem to be to my question, which I asked amiss.

I have rephrased the question just a few minutes ago.

But i am afraid i clicked Solved when i didn't mean to, and i don't see how to undo it now, altho i have seen a way to undo it before.

I've really messed up. It's probly too late and i will have to start a new question.

Thank you bery much for your help.
