If my reply gets you to stop posting in this thread my job is done. Listen, folks have been trying to give the best explanations as to why there is only one HMC allowed on an account at a time. Since most of the folks here are not DIRECTV employees and we have NOT signed NDA's people are just coming up with their best educated guesses. DIRECTV has their reasons as to why they have the one HMC limit at this time and they aren't saying. And until they do I guess you're just going to have to live with the one HMC answer or move to another company that will give you everything you want to pay for with no limitations.
