The tuning data accessed to create the WebIF display is static info from when the tuning occurred, and only retains the info for the last mux if tuned manually (or all of them if tuned by auto-scan).As I was tuning the signal quality and strength showed up as good on all channels though just now looking at them via WebIf only channel 24 shows a good signal. I haven't actually watched anything yet but previously never had any issues with picture so maybe its just the WebIf display.
The live tuning strength and quality are available on the i-plate (press "i", on-screen lower right) or better via Menu >> Settings >> System >> Signal Detection.
