Before I even get started on whatever I can find that relates to your layout, I'm going to make one comment: the site is too wide. You should be designing for 800 x 600 resolution minimum, or at the very least 1024 x 768. The latter is still the prevailing resolution.
As far as the movie not display goes, change param="main" to param="movie". If that doesn't work, steal some of my code and use it for your own evil purposes:

You'll see the Youtube vid. That's the Flash vid you'd want.
If you've uploaded your changes, I don't see the conditional comments LNR was referring to. You'll want to check out this page if you haven't yet:

It should explain things clearly. Basically, you just need to add IE-specific comments so that you don't mess up your other browsers.
If that doesn't work, you're going to hate my next piece of advice, but it will ultimately serve you the best in the long run...
restart from scratch. But this time around, start with a PC and open up both IE
and Firefox (ideally, IE6 since it tends not to play as nicely with FF and others as IE7 does). If you're really feeling froggy, download
Safari for Windows and open up a copy of that as well on the same machine.
When you've got the three browser windows open, take a section and code it. Check it in all three browsers. Correct as necessary (or ask for help on the section in here if you can't get it). Move on to the next section. Repeat until you've got all the sections coded.
If you can do that, you'll generally take care of your MAC users and most of your secondary browsers (e.g. Opera) as well. You may run into the odd issue here and there, but for the most part you'll nail 'em. You'll also find it much easier to take your code a section at a time, check it in all browsers, then move onto the next section than you will to deal with the issues that you're dealing with now.
And for the love of all that is good in the world, don't you
dare go back to tables. We'll have to beat ya if you do.
