one way to do it, which really has nothing to do with asp .net but rather html is like so:
<object width="320" height="290"
classid="CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95"
id="mediaplayer1">
<param name="Filename" value="kids.mpg">
<param name="AutoStart" value="True">
<param name="ShowControls" value="True">
<param name="ShowStatusBar" value="False">
<param name="ShowDisplay" value="False">
<param name="AutoRewind" value="True">
<embed
type="application/x-mplayer2"
pluginspage="http://www.microsoft.com/Windows/Downloads/Contents/MediaPlayer/"
width="320" height="290" src="/support/dreamweaver/ts/documents/kids.mpg"
filename="kids.mpg" autostart="True"
showcontrols="True" showstatusbar="False"
showdisplay="False" autorewind="True">
</embed>
</object>

another possible way might be to download the windows media player sdk thing and see if there is a control that you can use in asp .net. here's an example but this is in a regular .Net app, but may be somewhat similar to the way its done in asp as well.
