I have a recently purchased Onkyo 660 Home theatre system (HT-S3500). Everything is set up now and I absolutely love the sound quality however not everything has been brilliant.
First time I set it up my cable box worked however now it's not saying that the HDMI copy protection system has failed to initialise. I've connected this directly to the TV and am using an optical connection, not as neat but it solves that problem.
At the moment my Wii U, WD Play and Xbox 360 are connected. The surround sound works on all of them, however the Xbox will only display in 720p. If I set it any higher it results in the screen flickering every few seconds.
The Wii U (connected to the game port) is perfect at 1080p, the WD Play (connected to the VCR/DVD) port is also fine at 1080p.
The 360 is connected to the Blu Ray/DVD port, I have tried different cables and the result is the same.
Any suggestions to get this working at 1080p? Anybody had a similar issue with an Onkyo receiver? If you've had that issue with any other brands what did you do to solve it?
