I just had a Direct TV installer tell me that Direct offers the only "True HD". Dish he claimed is manipulated at the receiver and not true HD. This discussion came about at a rental property that is wired with undersized coax by modern standards, he claimed it would not transmit / work with Directs brand of HD. When I countered that my home had the same wire size and worked perfectly he countered with the true HD comment. I'm just wondering the relevancy of this... in how it relates to the real world ? I presume if you have a pre-wired home with so called undersized coax, Direct would not be an option for you? or would Direct TV attempt to sell a new coax wiring job to accommodate ? Seems to me Direct is manipulating more than a HD signal here. Any education on this would be greatly appreciated. Thank you, Chas.
