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.
