Multiple UStream Boxes?

I'm trying to make a gaming website. I just started working on this site and don't expect to be finished fully for a while.

But I have ran into a little problem.

I'm trying to set it up so I have 3 UStream streaming boxes set up horizontally above the Chat Box. I already have one set up but when I try to put the Embed code of the second one, the streaming box appears below it. I don't want the boxes to look vertical. My website is TheGlobalGamer if you want to go look at how my first box is set up.

Is this at all possible? I've seen one of my friends do it before but I have no idea how and he won't tell me.

Is there some sort of code I need to put in, or set it up a certain way?

All help would be appreciated, thanks!
