I'm trying to get smoother playback on my HDTV programs. I looked at the log from the frontend and noticed the message that tells me that my frontend is not setting realtime priority.

My /etc/security/limits.conf file is set correctly. No soap. I tried even using the old deprecated chmod a+s method on mythfrontend and mythtv. No soap. Nothing I do allows the frontend to set realtime priority.

What the heck is going on?!?

This may seem overly simplictic of me but is the option turned on in the settings.

Under: Utilities/Setup -> Setup -> TV Settings -> Playback

On the first screen there, the very first option is Enable realtime priority threads. I have just done a clean install yesterday of R5.5 and the box is already ticked on mine so I would be pretty sure it would be on for yourself already. Just a thought.

Yep! Thanks for the reminder, anyway.

From the Gentoo page I learned to check with


This gives me back "50" which is the correct answer if everything is working correctly. Yet the frontend complains that it can't set realtime priority. I scanned the MythTv archive and it says the message applies to either SUID or setting priority through rlimits.

Color me confused!

Does the mythtv user have sufficient privileges to use realtime priority? Sorry I can't provide more detail, but I've never bothered with this myself...

Joe, just out of curiosity, why do you use real-time threads? I don't use them and I don't have any problems with hidef playback.

My log would spit out errors when I tried to enable real-time priority threads as the mythtv user. If I ran as root it would not show that. I could not tell a difference between the two, but have since realized that I did not have real-time priority threads enabled in R5. Maybe it is something else causing your choppiness? I only use standard def so I can't be of much help there...
