If you want HD Superstaions get a Bell sub. They have WGN-CW9 Chicago, WPIX CW11 NYC, WSBK MY38 Boston, WPCH IND17 Atlanta, KTLA CW5 LA, CHCH IND11 Hamilton, ON all in HD. No WWOR though.
How difficult & costly is it to get a Bell sub, if you know...and are all those channels off the same sat location - 92?
