How to make a iframe

Any idea or Plugin to making an Iframe of a Video Site of a Particular Area to embed video only i.e only show the Media Player Part.

i try to use <iframe> </iframe> code but it shows upper part and ads of other site as well i jus want the Video part only to show on my site also try to view source and adding Video Part but the Links Expires in every minute of that site so i was thinking tht if any solution i can show only the Video part of that website on my site croping or resizing other part of the Site. It’s fifa WolrdCup2010 season so i m embeding Live Matches to get more Traffic on my site and want to embed video by making a iframe from other sites!!!!

i m not good in coding maybe i m not using iframe code well so if anyone can explian it would be great!

Thanks.
