Just a comment on Shaw Direct (StarChoice). They are no longer supporting use of their system outside of Canada. They have adopted the Bell Expressvu business mode and are trying to limit use of their product to Canada only. Well, they have not re-aimed the satellites so the signal is still there for the taking, just don't expect any help from Customer Service. They have not yet taken to cutting you off if they find you are outside of Canada but that could be coming.
Use the DishPointer site to get a good idea of where to point your dish but do not count on them for skew settings. They use a different calibration for their angles and they do not work with the Shaw dish. I have pdf documents for all the setup information including azimuth, elevation and skew for Canada, USA and Mexico. If you want me to email you a copy, let me know.
