Well having to resort to OTA, that I have ready for times like this, it really goes to show how much better the OTA picture quality is than off the dish. And I just had mine repeaked and a new LNB installed last week. Unfortunate reminders . . .
Are you implying that peaking a dish antenna and new LNBF makes the picture quality better? If it were analog, yes, but with digital, it is all or nothing, so a signal of 25-30% quality that barely gets a lock, but does indeed get a lock and has no macroblocking, will "look" the same as one with a 90% quality.
As for OTA looking better, I find it varies on the channel. Some of my locals look better on satellite. Depends on how many subchannels they have crammed in.
