Well there must be a way, because it's working for me.<br>
<br>
I'm using a Nvidia based Zotac ION frontend, connected over
HDMI to an<br>
LG television.<br>
<br>
If I leave MythTV on a menu then, after a while the screen
goes blank.<br>
A short while later the TV screen save kicks in and a short
while<br>
after that the TV turns off.<br>
<br>
The bad news is that I can't think of anything special that I
did to<br>
make this happen. (I use gdm to autologin the mythtv user
with a<br>
ratpoison window manager, and start the frontend). I haven't
changed<br>
any screensaver settings from their defaults, as far as I know
(which<br>
I think means that mythtv is controlling the screensaver using
DPMS)<br>

The original poster is using a Sony Bravia TV and you are using an
LG television so maybe the difference is the Sony won't respond
DPMS over HDMI. Just a thought.<br>

I think it is just a normal mode of operation. My Panasonic TV has
the same behavior. It is hooked to an Nvidia 8400 through HDMI. The
mythtv menus provide no change? in signal so the TV first blanks and
then powers itself off.<br>
<br>
I often use mplayer in a terminal to pull radio from a separate
system or an Internet feed. I have to use either mythgallery or live
tv to keep the TV from shutting off and consequently turning off the
speakers. The good news is that once the audio is coming from
mplayer, mythtv's audio is muted.<br>
