changing the default player in advancedsettings.xml is much more simple:
<advancedsettings>
<video>
<defaultplayer>externalplayer</defaultplayer>
</video>
<externalplayer>
<filename>C:\python26\python.exe</filename>
<args>c:\mplayerc.py</args>
<forceontop>true</forceontop>
<hideconsole>true</hideconsole>
<hidecursor>false</hidecursor>
</externalplayer>
</advancedsettings>
