This is a slighly modified version of the existing XBMC python video plugin called "TVServer" or "XBMP-TV" to extends XBMC with a MediaPortal tv client.
It has less functionality compared to the PVR client, but it is useful for testing without having to build the pvr-testing2 version of XBMC from source and for XBOX users.
Update: 01-08-2010:
Changes/bugfixes:
Download: TVServer XBMC Video Plugin 1.1.0.75

Edit TVServer/resources/settings.xml in case the "TVServerXBMC" server is not running on the same machine.
