predvajanje avi datotek v firefoxu

Zdravo,

imam en html fajl s to kodo:
<embed type="application/x-mplayer2" pluginspage="http://www.microsoft.com/Windows/MediaP... src="madmax.avi" width="240" height="252" autostart="0" showcontrols="1" showstatusbar="1"></embed>

V firefoxu se mi lepo prikaže okence WMP-ja, ko pa dam play, se ne zgodi nič. Če kliknem z desno in dam "Error Details", mi napiše to:
Windows Media Player cannot play the file. If the file is on another computer, verify that you are connected to the network. If you typed a path, verify that it is correct. If the problem persists, the server might not be available.

madmax.avi je v isti mapi kot ta html dokument.
Imam pa firefox 1.0.2, WMP 10 in vse plugine za FF
