Embedding Video

So you saw that I just did a video embed for payperpost on the last post I did. It took a lot of trial and error to get that onto my blog. So, I'm wondering what I actually did to make it work! And how to do it again? PPP uses Youtube.com, and they have a link to copy that actually says embed...so yes, I figured that is what I am supposed to use; however, it doesn't allow me to copy the embed link all the way. What's up with that?!? PPP has a few more posts that I can take that involve embedding video so I'm going to try it again, but if some of you have any suggestions, ideas, comments, or just want to say hi let me know....I really want to figure out how to work out all this blog stuff.
