I'm afraid i'm a bit unsure as to what your issue is. you mentioned in the subject you're having trouble recording, but in the post itself you mention name value,s, ip's etc.
Are you not able to RECORD MSN Webcam? Does
MSN Webcam Recorder support Vista at all? Do you have a 32bit or 64bit version of Vista?
Normally I would recomend a
Screen Capture program for this type of recording...
Replay Video Capture and
WM Capture should work fine for you, since both of them allow you to record both sides of the conversation (they support recording audio from 2 different sources like your Mic and PC speakers).
