YouTube + iFrames

So I learned that by putting videos in iframes they will start automatically upon loading. Upon learning this it brought up two questions. The first being, is using iframes on your videos against the rules of YouTube? Like will you get banned on YouTube if you do this or no?

The second, would be when I tried inserting it between the <iframes></iframes> codes as both the videos url and the embed code neither displayed even the video box. I want to use it in my wordpress blog.

Is there a plugin that allows this to happen or am I just using the iframes code incorrectly?

This partially deals with the youtube section and partially the wordpress. Thought it was better placed in here.

First question Idk.

Second one, you can create a bounch of 1px iframes. Easy as that.
You only have to put in the youtube url.. dus <iframe src="url"></iframe>

full code should be: <iframe src="url" height="1" weight="1"></iframe>
