Considering purchasing an ATV (would go Mini but not in the budget right now). Looking for some input from anyone with experience with the following components: * RCA 52" HDTV with 480 and 1080i capability, but it does not display 720 at all. * Onkyo TX-SR606 with 4 HDMI inputs/1 Out and 1080i upscaling. Reason for pause: I recently purchased a Blu-Ray player and could not get it to display running HDMI through the Onkyo, yet have DirecTV and an LG DVD/VCR player running HDMI through the Onlyo. The RCA has only one Component (used by Blu-Ray) and one DVI/HDMI input (used by Onkyo) input. It also has an S-Video and Composite input that are not currently used. If I can't run HDMI through the Onkyo, I would have to use S-Video or composite inputs to the TV which would degrade video quality. Anyone had experience with these components?
