Here is what I know... I live on LI and only receive YES HD on channel 95 sometimes. My friend also on LI gets YES HD all the time by going to channel 622 SD and then hits the channel up and it goes to 622 HD. I found out he has a H20 receiver and I have a H10. After numerous call to DTV I got someone who understood and told me I needed a receiver and dish upgrade. My upgrade is scheduled for Friday.... By the way the new reciever gives you other locals like 4-2, 4-3, 4-4 all NBC local but most of the stuff is junk..
