Video won't resize

Hi, my client is putting the video widget to the test. YouTube and Vimeo were fine, but we have a problem with a third one. A local TV station did a piece on her that they keep on their website. She wants to link to it but it doesn’t resize. I have tried adjusting the playerheight and playerwidth in the embed code but it doesn’t have any effect. It ends up fitting in the window with the right side and lower controls chopped off.

I can’t show you the site because it is in development ‘stealth mode’ but the embed code is <script type='text/javascript' src='http://KPTV.images.worldnow.com/interface/js/WNVideo.js?rnd=702242;hostDomain=www.kptv.com;playerWidth=640;playerHeight=400;isShowIcon=true;clipId=11731448;flvUri=;partnerclipid=;adTag=Video%2520Player;advertisingZone=;enableAds=true;landingPage=;islandingPageoverride=false;playerType=STANDARD_EMBEDDEDscript;controlsType=fixed'></script><a href="http://www.kptv.com" title="KPTV - FOX 12">KPTV - FOX 12</a>

Are there any adjustments I can make to get it to fit properly?

Thank you
