Posting YouTube Movies – Users

Hi Guys, I’m new to this forum. I’m a it of a novice I’m afraid! I’ve set up a blog with WordPress, everything working perfectly!

One thing though, only I as the Administrator seem to be able to post a youtube movie (using embedded code). I have set up a regular user as an author, and some mates have too, but as an author, you can’t post a movie. You paste the text in the HTML section and Publish, then to code just disappears.

I have tried all the different User settings, Admin and Editor can post movies, all others cannot.

Can anyone shed some light on this please? It is a simple setting or something?

Thanks in advance guys! I did search for this but couldn’t find anything.
Cheers
Ben
