I am finally getting my Direct TV installed after waiting 2 weeks after my purchase for someone to contact me. Is there anything I should be aware of when they come to do the installation? Are there any questions I should ask? How long should it take? They are going to install 2 systems in the house, and I am guessing they will have to replace the old cable wires as well not being up to the current standards. I would hate to miss out on a golden opportunity while having them at my house to answer or fix any potential problems or questions I might have. Any recommendations?
