I recently bought an Onkyo TX-SR706 AV Receiver. I connected my Panasonic Blu Ray Player, Oppo DVD player and my Comcast Cable Box/DVR to the three HDMI outlets on the receiver. This was connected to my RCA Scenium HDTV which has only one HDMI input. Most of the time I have the receiver set up for the cable box. When I turn on the equipment I get, most of the time, some video noise, unusable signal message, etc. for a short time before the picture appears. I have learned to make sure that the receiver remote is set to control the cable box. After this clears up I often have problems when I enter a new, not adjacent, channel on the remote. This problem does not appear when running through the channels in order. I also have a similar problem when I switch the remote control to the other two components, the Panasonic and the Oppo.
Any ideas on what I can do to correct this problem?
