Salve ho inserito mediapalyer in una pagina web con questo script:

<object
classid="CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95"
codebase="http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=5,1,52,701"
type="application/x-oleobject" width="300" height="26" align="absmiddle"
standby="Loading Microsoft Windows Media Player components..."
id="mediaPlayer"
style="WIDTH:282px;HEIGHT:26px">
<param name="SendOpenStateChangeEvents" value="true" />
<param name="fileName" value="http://radio.darkartika.net:8000" />
<param name="animationatStart" value="true" />
<param name="transparentatStart" value="false" />
