layout and quicktime issues with ie for mac

[IndustriousBird]

I just launched a site and it works and looks fine on ie for windows, and netscape and mozilla for mac, but it has issues with ie for mac. Specifically, I have two problems regarding ie 5.1 on mac os 9.2.2...

1) the main content table gets stretched to the right on ie for mac- creating unused white space that is not supposed to be there.

2. I can't get these quicktime movies to work on ie for mac.

Any help with these issues would be greatly appreciated. I'm stumped!
