Seems your site was made by some M$-Office related program, given the fact that is uses VML (although an approved standard, only supported by some IE-versions, and not recommended since svg and 9-scale-techniques)
Which results in code that's, well... putting it in a nice way: crap
I do love your scheme and layout, so if I have some spare time, I'll try to make a valid XHTML-backbone for a liquid layout. (Without 284 Errors from W3

although about 1/3rd of them are probably due to no doctype..)
If I grasp your idea correctly, your intention is to have 3 columns, of which the outer two are fixed in width?
The first column contains: part of the header, advertentions (should it stay 'in view', or just scroll along with the page?).
The center column consists of: the header/banner, a menu, pagecontent
The right one: don't quite understand the intention, since it's still empty, unless it's there for pure symmetry (which in turn is rather useless)
The pagecontent has some kind of news/items look, and each item has it's own grayish area, with a title and then actual content. (on the main-page I mean, videopage is for your own try afterwards

)
If that is how you want it, I could give you some clean code to start from if you'd like. Nevertheless:
if you want a good site, learn (x)html and css. Make sure you understand the code that's given to you and don't hesitate to ask about it.
And lastly, one point of criticism on the design. On the main-page, don't interrupt the blue background of the central content. I have the feeling that your page is made whilst having a hiccup or sth
Don't let my post offend or scare you in any way, it's always nice to welcome someone new who's willing to try and create stuff!
