Thanks for your reply. I got the latest (I think) release 
And it starts ok and displays other peoples video (when run under the 
AG3 client) but  my camera still doesn't seem to be recognized.
Or better I don't know how to configure the camera, as a video producer 
the only thing selectable is "x11".
Tom Uram told me to try it on the command line which I did:

/usr/bin> vic
Failed to get raw1394 handle - No 1394 devices
ioctl VIDIOCGCHAN: Invalid argument
Attached to V4l device: V4L1:USB Video Class device
ioctl VIDIOC_S_INPUT: Invalid argument
Attached to V4l2 device: V4L2:USB Video Class device

and it comes up ok but doesn't show my video and when I check "transmit" 
in the menu it segvs.
luvcview  works fine and captures video.
Any suggestions?
