On a couple of different days now the first time I try to use my Roamio it's not outputting anything over HDMI; no video or sound. The green circle is on and the yellow circle flashes ever time I press a remote button. A cold restart restores function. Its HDMI output is routed through an Onkyo TX-NR515 AVR which has been in standby mode for several hours; the same hook-up worked fine with my basic Premiere. Has anyone else noticed this?
