Recording P2P TV streams (TVAnts mmst:// Windows Media streaming)

Hello: I've been trying for weeks now to record P2P TV streams that are generated by a P2P application called TVAnts (www.tvants.com).
The suggestions posted on this site don't work since there exists no single URL (in the conventional http://... format) for the stream. Using mmst://localhost:16900/1 etc also doesn't work with WM Recorder, PPRecorder, etc.
Is there anyone who can help me with the recording.

Many thanks,
Sonya
