I have tried compiling myth myself on this box, but there is something missing
that causes the compile to fail - perhaps I should start another thread to
try and solve that problem.
I want to use the nvidia driver because I haven't been able to successfully
configure the nv driver to work with xinerama.
The CPU Load is running at between 5-10%, so I don't think that is very high
(it seems to be the same when I watch Live DVB TV.
I have tried removing "Load glx", but it hasn't made any difference.
