Make sure you have the H20 set to only send out 480i and possibly 480p resolutions if your TV supports 480p. You might currently be trying to send 720p or 1080i over component to your SDtv and that is why it isn't showing anything, it can't understand the HD signal.
I think my issue actually is the signal strength but I don't know what's wrong. In the basement on my HR21-200 I get 80s and 90s on 99c, 103ca, 103cb and 103s, transponder 21 (where my HD locals are). However, on my H20-100 when I check signal strength I get all 0s on 99c, 103cb and 103s transponder 21, but get signals on 103ca, so if I tune to ESPNUHD, for example, it shows up fine on my SD tv hooked up to the H20-100. Can anyone make sense of this? Even just a way to get the 103s signal on the H20-100. Thanks. I have a Multiswitch with 2 lines running to the basement and main level, but only one cable hooked up to the H20-100 as it only has 1 tuner input.
EDIT: Is the issue that I don't have a b band converter on the back of my H20-100?
