When hooking up the new "Genie" DirecTV HD-DVR system to my processor, I have noticed a difference in performance between the use of HDMI-A (auto-signal detection) and HDMI-S (S/PDIF) when these are chosen as the audio setup options in the processor for the incoming signal. Since I know virtually nothing about how these two protocols operate, it's time to do some learning.
1. With DirecTV, the HDMI-S captures the audio signal much faster and more reliably. With HDMI-A, I often lose the signal when changing channels, etc., resulting in no sound.
2. I had noticed that some stations were broadcasting in Dolby DDPlus, but no longer see this. Can HDMI-S carry DDPlus, or is it bandwidth-limited to the standard Dolby signals? It does pass Dolby EX.
So, in getting this hooked up optimally, I want to know if using HDMI-S loses any audio potential. As HDMI-S is the signal that doesn't have drop-outs, that's an advantage.
