The nvidia devices that you're likely using are not writable by
non-root.  As you are likely running as a non-root user, you should do
something like chgrp the devices to the 'video' group and add the user
that MythTV runs as to the video group.

I don't _think_ so.  Not if you're using an nvidia card.

Check the permissions on /dev/rtc and check to see what
/proc/sys/dev/rtc/max-user-freq is set to (I've got it set to at least
1024).
