Stick to your guns man, just keep calling them and get the best deal out of them you can for the cheapest amount and just add it to one TV, if you do have the extra $40 or so per month it would cost.
I never bitched about comcast until about 4 years ago when I switched from TiVo, to their DVR. It is terrible, flat out. If you have never used another DVR then you wouldn't know any better. It's kind of like HCP before he hit it big time. He lived on top ramen and cardboard pizzas, then he trapped his gorgeous wife by knocking her up and she changed his ways and introduced him to many finer things in life.
I was "raised" on cable TV, AT&T, comcast, etc. Then DVR's came and I was all over TiVo, they slipped and Comcast offered an HD DVR so I jumped ship from TiVo and I realized going from HCP's gorgeous wife and fine foods to expired cardboard pizzas and over cooked top ramen, that it sucks. I later had issues with my home phone as well and then they "added more HD channels than ever before" meaning they recompressed all of their content so they could reduce the quality to give consumers more channels, I bounced to Dish who has the best DVR available today. Then Dish lost ABC so I bounced to Direct, their DVR is alright but they also have the most HD channels so I was willing to deal with it and they are always rolling out new features, something I don't believe Comcast has touched with their DVR.
Yes they do have a deal with TiVo to someday release TiVo software on their DVR but that was announced 2 years ago and still isn't here, at least in our area. MAybe that would make it usable for me again. So in short, if you've never experienced the gorgeous girl, or then name brand food, you don't fully understand what a crappy product really is.
