One of the following three is sufficient, in order of decreasing security:
1. Use kernel 2.6.12-rc3 or later, and set up RLimits to allow
realtime priority as discussed here:
2. chmod u+s mythfrontend -- this will not work on Fedora Core 3
and possibly other distros that use the selinux patches.
3. Use sudo to run mythfrontend as root:
i. Need to modify /etc/sudoers to add your mythtv user
(use ALL option and NOPASSWORD; example in sudoers file)
ii. Start mythfrontend with sudo: "sudo mythfrontend &"
