Hi All,
I recently purchased an Onkyo Amp and happily plugged all my HDMI sources in. TV is a V series 40" Sony.

All went well for the first few days, DD audio through HDMI, TV controls volume on receiver etc very cool.

However since then we have been getting random HDMI dropouts when watching Sky. While a show is playing the TV will go blank, then the MySKY HDCP error will come up, then picture will come back. During this time the HDMI light on the Amp will be flashing, indicating a renegotiation.

Issue is intermittent, appears to happen more often with recordings.

Having done a bit of research I am not the only person with this issue:

and numerous others.

The decoder is the standard MySKY HDI box, with latest firmwares (I believe).

I initially suspected the Amp, but I am able to watch other HDMI sources (Blu-Ray, Laptop using HDMI) without any issue for hours on end. 

Things I have tried:
1. Moved decoder to better ventilated location
2. Changed output to 720p, 1080i and Auto
3. Tried different HDMI ports on Amp and TV

I have emailed and spoken to Sky and explained the issue. The lady I spoke to couldn't understand how I was possibly getting an HD picture through a receiver and even checked if I had an HD ticket.

When I explained the issue again I was told that the box is designed to only be plugged into a TV and they wouldn't send a technician out to troubleshoot customer equipment and that the HDMI/HDCP problem is not their fault.

When asked, plugging the decoder into the TV is the only situation they will support and do anything about.

When I plug it into the TV it works fine, but that sort of defeats the purpose of having an HDMI Receiver.

Has anyone else had the same experience and had anything more helpful from Sky?

I see I could purchase a 3rd party receiver (like the vu duo) but suspect that would not sit well with the wife.

Cheers,
-Jeff
