[mythtv-users] Higer load in .20

[list at onnow.net]

I think there may be a bit more system required for .20
RAM especially I think.
This system is a an AMD 3200 with 512 running FC5 and .20 via RPMS.
On this top, there is nothing running other than mythfrontend.
No encoders are recording.  Live TV may be on but that is it.
Check this TOP out.  Any better ways to diagnose what the load/mem use is?
