i've been running 3.2 beta on my macbook pro for quite a while.
after some software updates a couple of months ago, my
VideoProducerService/VideoConsumerSerice configuration would no longer
show me my USB camera video stream.  rather than checking the logs
and trying to figure out what was going wrong, i opted to try
removing the vid producer and consumer and added a VideoService.
i could see my video stream again.  that's the configuration i'm
still running.  i guess i should have filed a bug report.  sorry, Tom.

if you haven't tried VideoService already, you might wanna give it a go.
it works for me.
