what you are trying to do is not supported, check out our doc on iFrame. http://support.ooyala.com/developers/documentation/reference/player_v3_dev_iframe_nonwindows.html
You can embed with IFRAME, but the interaction via JS is not possible.
BTW, we have a support community: http://community.ooyala.com/ Check it out when you have technical questions. :-)
