Trouble adding Youtube embedded media

Hello everybody,

I’m having trouble adding an embedded media within a post.

When I’m logged in as administrator and add a media embedded in a youtube post is okay, everything works perfectly.

When I’m logged in as User and add a media embedded in a youtube post and click publish media that was built some. I tried to observe the html tab and yet contains no code flash.

Could someone tell if a problem or something questeja doing wrong.

I am using wordpress MU

Thanks friends,
Marcelo Wanderley
