Thanks for your help.  I've made the change in the frontend to
/dev/video0 and I also chmod 777'd the /dev/video* devices.  I am
still getting the black screen, but here's the most recent output; I'm
going to highlight the pertinent new error:

2005-02-28 12:37:14.512 Changing from None to None


Can you point me in the right direction?  Thank you very much for your help.
