You can't embed an MPG video with the "Flash" option.
Try using this code, substituting the things in RED.
Code:
<OBJECT id='mediaPlayer' width="419" height="259"
classid='CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95'
codebase='http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=6,4,7,1112'
standby='Loading Microsoft Windows Media Player components...' type='application/x-oleobject'>
<param name='fileName' value="http://servername/path/to/media.file">
<param name='autoStart' value="false">
<param name='showControls' value="true">
<param name='loop' value="false">
<EMBED type='application/x-mplayer2'
pluginspage='http://microsoft.com/windows/mediaplayer/en/download/'
id='mediaPlayer' name='mediaPlayer' displaysize='4' autosize='-1'
showcontrols="true" showtracker='-1'
showdisplay='0' showstatusbar='-1' videoborder3d='-1' width="419" height="259"
src="http://servername/path/to/media.file" autostart="false" loop="false">
</EMBED>
</OBJECT>
Also, it's not a good practice to have spaces in your file or folder names. Consider renaming the folders, or if you must have spaces, substitute %20 for the spaces in your HTML.
