I use what's described here:

http://www.mythtv.org/docs/mythtv-HOWTO-5.html

...in the section marked "Enabling real-time scheduling of the display
thread".  It requires having PAM version 0.79 or above (I have
sys-libs/pam-0.99.9.0 installed under Gentoo), and having this in
/etc/security/limits.conf:

*               -       rtprio     0
*               -       nice       0
@audio          -       rtprio     50
@audio          -       nice       0

That's always worked for me.  I get this in my mythfrontend.log:

2008-03-19 01:32:17.500 Using realtime priority.
