That would be very strange if xinetd did anything to any screen saver
settings, since it's a network server only and unrelated to Xorg. A
while ago, I had the same problem that you had. I had used 'Option
"BlankTime" "0"' in the ServerLayout section of xorg.conf. Then, after
upgrading Xorg, the screen started blanking, so apparently Xorg had a
regression that caused it to ignore the blanking option. I managed to
fix it by running "xset s off" in my mythfrontend session startup
script. The xset command is a regular X11 client, so running it at the
beginning of the X session is appropriate. As you discovered, you can
run it from cron with "-display :0.0" as long as that's the correct
display, but that's ugly.

I'm not sure if you encountered the same bug, but there are few things
as frustrating as software that silently ignores documented configuration.
