[AG-TECH] AG 3.2 on OSX

So I was doing some more testing today. Here is where I am at. I can get the
VideoConsumer Service to work but no VideoProducer. When I try switching to
just VideoService on it's own, I get an error saying "Error enabling

But if I enable VideoConsumer service first, I can enable VideoService (I
know it is redundant), but I still am unable to select my built in camera.
If I try VideoProducer, I am not able to select my built in camera. I am
able to see the other node's video.

I am running it in a session with another AG node to see if there is any
video coming through, and there is not.

In case I am missing something in the start up, what is your usual sequence.
I start the Service Manager, then Launch the Client.

Any advice?

My system specs are MBP 2.8 Core 2, OSX 10.5.6, AG 3.2
