You may not know the answer to this but looking at some of the info for EDID, I am confused what the static EDID in tthe HDS-42AVR buys you.
All the video processing is between the source components and the switch and the switch and the TV. The only video flow between the 975 and the TV is it OSD.
Is this more to do with audio capabilities between the source devices and the switch that are passed off to the 975?
Just curious if you know.
