Update: Some say that only Admins can post…which makes no sense at all. I’m checking into that.
I was going to make this a private page just for my fellow Monitor Duty authors, but then I realized that there may be many non-MonitorDuty users who could be having the same problem and this might come in handy.
Everyone else can just skip this post. No geek goodness will be discussed herein.
I can’t believe Birds of Prey was canceled. I loved that book. Oh! Oh, right. How to do a YouTube video in a WordPress site.
My guess is that most of you are trying to do it via “QuickPress”, the little area on the Dashboard home page.
Don’t use QuickPress.
Don’t ever use it, really, since it doesn’t offer categories and tags, and I want everyone who posts to categorize their post and, if possible, tag it as well. Otherwise, I just have to clean up the posts later.
What you want to do is go to the “Posts” section and choose “Add New”. (Your view may not match mine, as I have Admin level authority and I’ve applied a style to my view, but you should be able to find it.) 
When you are ready to paste in your YouTube video code, click the right tab that says “HTML”. 
Then, paste in Embed code for the YouTube video. You can then either switch back to “Visual” for further editing/writing, or hit “Publish”. 
Voila!
Oh, you can also use the “Embed Video” icon and just paste in the URL for the video. I’m going to test that out:

Doesn’t look like that worked. What ARE they smoking over at the WordPress documentation site?
I did all that stuff… in that order… about five or six times over the course of an hour….
Wow.
Just hacked off it worked for you and not for me…
Only admins (like Hutch) can embed videos on wordpress; since we have author status and not admin status, we cannot– wordpress just deletes the embed code whenever we press publish, as explained here: http://wordpress.org/support/topic/233745 .
I had the same problems with my earlier post.
