Hi,
I have the following problem with openelec on the pi. If I connect the pi through my Yamaha RX-V475 AV-receiver everything is fine until xbmc starts, but then the connection between the pi and the receiver doesn't work anymore.
My TV switches between a black screen (maybe from the avr) and xbmc or it shows "no signal". The hdmi input/output status on my receiver blinks irregular, because it can't get a stable connection. I tried the latest openelec beta (3.95.5) and the stable version. Both don't work. If I connect the pi directly to my tv the problem disappears. With an other receiver (RX-V471) and an other tv the problem also doesn't occur. I tried different hdmi cables and inputs of the receiver. HDMI CEC is disabled in XBMC. It seems that there is a problem with the pi and the RX-V475.

Have you tried boosting the hdmi signal: http://elinux.org/RPiconfig
There's a couple to play around with you can start with hdmi_safe=1 and see if you can narrow in the exact course if that works.. Or individually for example hdmi_boost=4.

I'm not sure it will work wonders but its worth a try?
