Hi there,
I've got Russian package from nextv, may be 2 month. So far everything works fine. No pixelization, no black screen as it happened with my previous provider.
May be your problem is your internet provider? I have Sympatico, DSL and several of my friends switched from Rogers to DSL. With cable provider is not only the speed, but how many people in your area are Rogers' subscribers.
My advise - try to watch your Wave receiver at your friends who has DSL internet. You will see the difference.
