I had both Bell and Star choice at the same time, this was about 3 years ago, but at that time Star choice killed Bell for pq, bell was unwatchable, I have not seen star choice in a while but saw Bell HD the other day and saw a ton of macroblocking I'll stick with 4dtv
I would much rather support Star choice anyway, Bell has a big piracy problem, and they are causing many losses for other company's, I guess it's market share they are after, and there customer service stinks, whatever system you go with get a bigger dish, it will help with rain fade.
