I just had the H10 receiver installed last night - but watching an HD channel - how do you know you are actually receiving it in HD? I'm using the component hookup. Is there something you have to turn on - also - is there a way to tell if something is broadcast in 5.1 audio? And for over the air - I'm about 60 miles from all the Syracuse digital towers - any OTA antenna suggestions. I'm picking up one station with a 65% signal and the others are in the 30% range and don't lock in. Thanks for the help.
