I'm not on a windows machine ATM, but I would suggest going to the Youtube video that you are embedding and get embed code, then manually paste it into another node.  If it works in that one, then there is something the embed module is doing wrong.   So then do a view source on the embed module's page and see what's the difference between the code you got from youtube, and the code the embed module makes.

<div style="">Does anybody have any insight as why video clip embeds do not appear in IE6? I am running the embed module and have identifies which services I've allowed. Is there anything I may be missing?&nbsp;<div><br></div>
