I'm sorry if I wasn't so clear in my goals.
I'll try to explain this better:
I've a miniserver with slow CPU (just 1.5ghz) that i'm using for stream
files via samba or dlna, for dvb-t recording and p2p downloading (amule
adunanza and torrent).
The problem is this computer has all time an high % of CPU usage, adding
motion I get often 100%..
*I want to know if is possible reduce CPU usage only during the "not
recording time", I mean when it is in Idle, for example by reducing fps
while idle and increase to max when recording..
Is all this possible ?*

I'm using yet nice to get maximum priority during dvb-t recording :) but
