Troubles posting from abroad !!

Hi.
I’m part of the team http://www.goodmusiconly.com ( on wordpress 2.9.2 )
I live in London but the other members live in France.
The thing which is really weird is that they have no problem at all when they want to make a post with a youtube embed code in it ( <iframe etc .. ) but I do have issues to do that.
Actually when I try, instead of seeing the video, the code appears on the website ..
I put the code <iframe.. in the tab “visual” but I also tried to put the old html code of youtube. Didn’t work either..

I’m pretty sure it’s about being abroad, because another member was in the US in holidays, the same thing happened to him..

I told the admin to update wordpress to the last version, maybe this bug has been fixed since.

Any Idea ?

Thank you all
