TVU Player via MediaPlayer (freecom) & LAN on TV

Hello,

shortly I am using a so called MediaPlayer (Freecom) to watch some of my movies (divX, mpeg, etc.) on my TV. That works very fine. Also, I can watch over LAN movies that are stored on my PC on my TV. So, I asked myself if it isn't possible to play the channels that I pick up with the TVUPlayer also over my TV, using the network (LAN) and the mediaplayer?
I have no TV-Card, so I have and want to use my MediaPlayer, if possible.

Does anybody has some experience with that?

Just to explain more: The MediaPlayer (MM) is connected vis LAn with the PC and with composite to the TV. Over the MM i can pick files (divx, mpeg, mp3 etc.) from the PC and klick to start them to watch them.

Thanks so much for any suggestion.
