Not if you have a server. I have a 4 card system and the timers are
regularily updated by epg2timers and occasionally by vdradmin. My server
box currently uses about 180W 24/7. This means about 200 EUR per year
only for power. 

I vote for a *soft* standby mode activated by the user which powers down
the primary card, and an automatic standby of secondary cards when not
in use. The epg scan could be run every few hours and/or after a
recording on one of the secondary cards have been terminated.
