Which transponder to use when pointing dish

Hey andy, why don't you find a local Dish retailer who has a showroom and sample those channels at his location. If they are equally bad, then you know that is a broadcast issue that you can't do anything about other than complain. However, if he has no artifacting at his location, then the problem is likely specific to your location.

yeah that's good idea..I will try that.

do you know if the bandwidth can be dynamically controlled, so that channels are more compressed in certain locations in the country than others? I don't think it is possible..but just curious.
