Ok, if you want, H1 won't clear ss2 hd or the hd movie channels on my weak signal, but hey how what do I know about MY set up and reading the manufacturer s specs, Anyway I ended up with USB tuners on my vu boxes, worked much better for My needs, I have an ibox3 that I pay with and had same tuner as H1 but not H2. Same issue on ibox3 as H1 on my signal, same channels tune failed but I bow to your superior knowledge. Cheers.
