Webcam Loading

I'm using WLM and am trying to send a webcam picture using my Sony video
camera on firewire. I go thru all the setups and have video and even have
video on the messenger conversation screen, but it just says "webcam loading"
until it times out. The offer to receive webcam has been accepted by the
other party, but they never receive video. Same thing happens when they try
to send we a webcam shot, eventhough they are using an actual webcam. Tried
video phone and get the same result. I tried searches, but never got an
answer.

Anyone? Thanks
