I am upgrading my 942 to 622, and the installation will be next week. Currently I am pointing to 110, 119, and 61.5. Are new MPEG4 channels on 129? Do I need to point the 61.5 dish to 129? If the installer offers to replace my 2 dishes with 1 dish, should I do it? Or am I better off leaving it as 2 dishes? Any help would be appreciated. Thanks!
