How do you do run mythfrontend suid. I will search for this in the
archives.

<pre wrap="">Thanks.
I just tried it. And, when FF the video just freezes and I get the
warnings:
"prebuffering pause"
over and over. Had to Ctrl-C out of mythfrontend
I also get the warning (when going to HD content):
"realtime priority would require SUID as root"
After I:
chmod -s /usr/bin/mythfrontend
Then, no problem (except of course, the original problem of frames
that jump around when when the OSD is present. BTW, I tried this on
two programs Lost and Dancing with the Stars (both ABC, SF
Bayarea) - both had stuttering audio with the frames. So, I guess
I was wrong about saying that the problem was only video)

note that I always had that on. It's when going suid that it freezes.<br>

Guess there's a reason for the warning :-)
What's your CPU load when playing without suid?
