Incidentally, in other version of MePo, I never had to do this.........has something changed?
My experience agrees with the original poster. When I installed MP 1.9.0 pre to use as my "production" system, the "PowerScheduler" plugin in that version of MP was disabled by default (I did a completely new install, not an update install). The "trial" system that I had previously installed some months earlier (MP 1.4, I think) had "PowerScheduler" enabled.I don't know what version of MP you were using, but nothing has changed particularly recently.
I have been using MP as my HTPC for 3 months now, and I did not really pay attention to MP developments prior to that, but my recollection is that there was "PowerScheduler" that was built into MP, and there was a separate plug-in called "PowerScheduler++" which replaced "PowerScheduler" in MP when the "++" version reached a sufficient level of maturity (in MP 1.8 or 1.9 perhaps?). I am happy to have my possibly-faulty recollection corrected.
Perhaps the default setting for "PowerScheduler" in 1.10 should be checked, and changed to "enabled" if it is still set to "disabled"?
