So I now have Handitv, and TCPMP

I've been having problems getting WMP to play any of the streaming videos, and was told TCPMP could do it (so I installed it)

well, i went into settings, and checked almost everything to be associated with it.

However when ever i try to stream from any program (like handiTV) it keeps opening WMP, and not TCPMP

so I am still unable to stream, any help?
