[Most of your standard definition channels are beamed from 101ºW]

1-8 95 100 95 84 96 100 95 100

9-16 93 100 97 0 97 100 96 100

25-32 96 69 96 100 96 100 95 100

So this is my deal. Most of the HD versions of a STD def channel are unavailable, I have exhausted every possible attempt to fix myself. This calls for service help.
