For those who are interested by the subject, I'm also trying to get a new option on plugin PowerScheduler++ to let the tvserver going to sleep when no needed (so not using tvservice) EVEN if a client is still running. My main goal is to wake up tvserver PC only when needed with WOL-Powermanager (eg : entering in tv windows) and let going to sleep with powerscheduler++ when there's no more tv streams. Look at this thread.
