Well last weekend after two different techs came out (one on Friday w/ 2 S-cards and one on Sat with 1 M-card) nothing worked. I got the basic channels, but nothing in the HD package and none of the channels above 100 on the SD TV. Anyway, I had all but given up, Sunday came, still no change - EMMs=0 then got the urge to call and complain about the install fee around 2pm on Sunday. They patched me through to various people (none of them right). Wouldn't change the fee, but did tell me that a local tech was coming out to try and fix things on Monday. Then I was scanning the channels about an hour later and noticed the channels all came through! I got everything - perfectly (with the single M card). EMMs not reads in the hundreds. Tech still came out on Monday even though my wife told him it was working and he checked everything, apologized for the inconvenience, and said we wouldn't be charged for the install. So, M-card in HD TiVo working in Chapel Hill area - maybe they are starting to get it.
