How do you figure?
Do the KA signals not reach off shore?
Also, did anyone ever consider that most MPEG4 HD will likely go to 101?
"Most" MPEG4 HD can't go to 101, there isn't enough bandwidth. It also doesn't make a lot of sense, why would they try to crowd 150 channels on 101, leaving several dozen idle transponders on 99/103? If they don't plan to have MPEG4 SD duplicates on 101, it would make more sense to 'spread out' and increase the bandwidth for all their HD channels, and have PQ that's significantly better than any other cable/satellite company.
