Page Menu floats under a youtube video

Thank you Flynn and Juggledad. You have made my day to respond so nicely and timely to the problem. Although it is not solved in a easy way at least the workarounds works. Thank you. I still have to try out Flyn's suggestions though.

But i must also say that this behavior of the youtube video is the first time i experienced it. I have other sites running with menu's and the menu floats above the youtube. I dont know about youtube's intentions of wanting to be ontop.
I think the menu in the atahualpa template is fairly complex with so many variables, that somehow or other some settings might not be interpreted the way it reasonably should.
What to do.. The CSS world is littered with broken rules/regulations/platforms/browsers. sigh...

Thanks for the good work.

P.S is there a snail mail address available to send something to you?
