i just got off the phone with dtv i was helping my dad do the directv movers choice. he has an hr24 and an h24 and at the new home will need to feed 8 TVs total now; i asked them to add an hr34 to the bill instead of adding many dvrs, but the other boxes to add HD boxes. at first she said the promo was 2 free hd boxes, but then she said he would get the HMC for $126 with shipping; and he should bring his two boxes with; but there was no need for any additional boxes. she said its a new hmc receiver that sends signal through the coax and would support the new tv's they can watch hd tv independently and record shows/watch recorded programs. is this some new technology that ive never heard of or something that doesnt exist?
