Will try to set up with HDMI only.
Thanks for the help----------------
If you still have issues with HDMI even with box set to 1080i only; another option is to use the receiver's HDMI output to display and connect all other sources via HDMI, but use component cables+digi coax or optical for the cable box (which will be limited to 1080i and 'lossy' audio even with HDMI).
The receiver will transcode and upscale (if desired) the component inputs to the HDMI output. As with the HDMI inputs you can tweak the video processing or have the extra
enhancements off (cannot be turned off entirely, of course)
This leaves only one connection to the TV, using the receiver to switch sources, allowing full 7.1 lossless streams from the HDMI sources, and keeping the AVR's GUI/overlays.
This is how I have my system configured. I have two comcast DVRs (moto dcx3400s), one connected to the 7550 and another connected to a AVR254. Both had issues connected directly to the HKs using HDMI (most often, no picture on start up or intermittent picture/flicker for ~15 seconds) despite being set to 1080i only. I don't blame the HKs as the boxes are quirky even with a direct HDMI connection to the set.
Using the component connection from box->receiver, boxes still set for 1080i output only and receiver configured for 1080p output, performance is flawless every time. I did not notice any real loss of picture quality, using decent quality component cables.
