FX HD seems great tho!
So this ESPN thing - do we get the premier matches in HD?

I'd say call VM - it could be a simple fix like boosting your power.

Go into Settings / Technical Stuff / Page 2.
You want SNR to be high (>30dB), AGC to be low (<80%), Pre RS Errors to be 0 (a small number are correctable), Post RS Errors to be 0 (anything else will cause pixies and chirps).
I base these figures on my setup. Your experience may differ.
The values will vary greatly from one channel to another. I typically find the documentary channels in the 200 range most prone to problems. They are ususally borderline with SNR at 28dB to 29dB and AGC at 90% to 100% with some occasional Pre/Post RS Errors. Nat. Geo. HD is likely to be in a bad frequency range requiring a lot of bandwidth and so prone to errors.
Check your readings on channel 232 then check all your connections on the wall socket, any splitters and your STB then take the readings again and post both sets here please.
I have more to say on the quirks of this problem but I'll post that later.
