Thanks Chris,

I think I get it. In concept, the Myth's backend's performance will benefit
from root's authority: higher priority, Real-Time Scheduling, etc. Therefore
/dev/video0  should be root owned as well. Problem -- how to allow non-root
(running mythtv-setup) acces to /dev/video0? Options: change perms of the
backend and lose performance, or give a user the perms of root -- SUID. I
vote for option 2.

Man! was my life miserable until I commented the "skip networking" line in
the mysql config file. Just one litte # and poof! I can watch TV in the
kitchen. These were my Knoppmyth days.

Accept during mythtv-setup? Nearly every HOWTO says to do this step as a
non-root user.
