[mythtv-users] Any tweaks possible for a remote frontend?

[rawgarlic at gmail.com]

The backend has been a Ubuntu 10.04 (Gnome) desktop for several months.
A few days ago, I installed the myth backend+frontend on it.
Configured it with a HDHomeRun tuner.
I can see all the channels HD and SD on the local frontend.
Everything works.  Its great.
Running top shows the CPU steady at about 15%.


Then there is a Ubuntu 10.04 (Xubuntu) desktop.
I just installed the myth frontend on it.
Pointed this remote fronted to the above backend.
I can see all the SD channels fine.
Running top shows the CPU steady at about 40%.
But when I change to any HD channels, only the audio works.
There is no video.  It is all black.
Running top shows the CPU steady at about 95%.

I understand that this remote frontend's CPU may not be enough for HD channels.
Just wondering, given that:
*  The CPU is at 95%.
*  The only half the memory is being used.
*  About 10% of the swap is being used.

Is is possible to change some myth settings on this remote frontend?
So that I can use it to see the HD channels too.
