I emailed Cignal's costumer service yesterday, inquiring if channel 109 is really an HD channel, not an upscaled SD in 16:9 format. Their response was:
"Yes, History channel is indeed HD.
What about the resolution settings?
Feel free to let us know if there is anything else that needs clarification.
Sincerely yours,

So I watch History channel again, trying to observe something. Then I notice that " Pawn Stars" will be "simulcast" in History and History HD..
I assume Miss Glaisa did not know about it..
