Yo uso videos en formato WMV y los veo mediante el siguiente código:
Código:
<object classid="CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95"

<param name="ShowControls" value="1">
<param name="ShowStatusBar" value="1">
<param name="ShowDisplay" value="0">
<param name="DisplaySize" value="0">
<param name="Autostart" value="1">

<embed
src="videos/video.wmv" width="320" height="300" autostart="1" loop="0" align="middle" type="application/x-mplayer2" pluginspage="http://www.microsoft.com/Windows/MediaPlayer/download/default.asp" showcontrols="1" showdisplay="0" showstatusbar="1"

AutoStart 1 = Parte solo. 0 para darle play manualmente.
