Opera div overflow:hidden youtube problem, please help!!

I tried searching on google but just can't find a fix for my problem.

So i have a div with fixed dimensions set to overflow hidden. Inside this div i have several youtube movies. In all browsers this works like a charm but in opera the overflow:hidden isn't working at all.

I tried to use overflow auto and all others, but the youtube movies keep breaking out of the div.

Is there anyone who knows how to fix this???
