Sorry if this has been mentioned before, if you experienced problems like slow response of switching between channels or menus with this update like me, just reboot your TiVo box, hay presto it then works fine!
Finally a dumb question about this energy saving feature, is it just for forgetfull or lazy people who don't put their box in standby mode when not watching TiVo, as if you put your box in standby anyway you are not saving any more energy after this update?
