I do know for a fact that if choosing to watch HD channels via a satellite, C-band (those real big dishes) has overall higher picture quality on larger screen tv's then by using Voom, DirecTV, or Dish Network. Big dish signal is the actual real signal sent to cable headends, while mini dish is overcompressed and retransmitted. I am not exactly 100% sure how it compares with cable tv or OTA tv. I have a link for their forums if anyone wants to check it out.
