[AG-TECH] Problems using webcam?

[Michael Miller]

Todd, Doug,

So I finally got the Fedora 2 kernel upgraded and the pwc module is 
loaded.  I went and got Doug's updated vic from the tar file and put it in 
/home/mimiller/.AccessGrid/local_services/VideoProducerService

I moved the old one out of the way of course.

However, I still get the green screen from the QuickCam.  Did I put the new 
vic in the wrong place?
