After digging around at the Media Player Object Documentation, it would seem that the thing (MediaPlayer.MediaPlayer) is actually an ActiveX control that needs to be embedded in an ActiveX container like a VB form or a web page in Internet Explorer. This was confirmed for me when I saw this. The author of that web page created a wrapper around media player and a scriptable object to create forms to embed ActiveX controls in. Give it a look as it may help. It relates specifically to WSH but you can translate alot of VBScript to perl using Win32::OLE.
