I have a Sony HDTV connected via HDMI to a sony HTSS-360 receiver and the PS3 is connected to the receiver in addition to an HDMI coming from my PC. Every time I turn on my TV/receiver, the PS3 ALWAYS powers on. Now, I do have control for HDMI on; HOWEVER, i turned off all the auto-power-on or auto-power off settings. What's even weirder is that the SAT input that I have my PC set to seems to be overridden with the control for HDMI input of the PS3 (when I output my computer via HDMI, it says PS3 input and when I switch it to SAT, it makes no difference).
I never had this issue with a set-top blu-ray player... seems to be the PS3 doing some overriding on HDMI. Has anybody else had issues like this with HDMI (or control for HDMI) with their receiver/PS3 setup?
