I have been trying to get this problem resolved for two weeks now and after getting no help from my local cable provider, Knology, and experiencing disappointing customer support with TiVo, I figured I would try you folks. The long and short of it is that Knology is convinced that their cable cards, the Scientific Atlanta brand, will not work with TiVo Series 3. I have had an installer come out four times during this time frame with the end result being that I have had exactly one cable card installed...and it didn't get any digital or HD channels, simply the low band ones from 2-77. Knology is refusing to do anything else to address the matter, saying that the problem is on TiVo's end. Now, Knology is a small company that is frankly bush league in every regard and the only reason we use them is because there is a contract in place that makes them the only game in town. DirecTV won't even work here (and yes, I know that a satellite solution would rule out TiVo, but I hate Knology so much it's become a reasonable option). So, I am fully willing to believe they are just in over their heads in terms of the next wave of technology. Frankly, even getting them to bring out cable cards to test is akin to asking for plutonium. For their part, TiVo keeps *ahem* forgetting to call me back after promising that they would be able to train the Knology dispatcher to install functional cards in the boxes. They have also indicated that they can and will start a class action suit against Knology if need be in order to make sure the cable provider meets the expected terms of cable card licensing. This sounds swell save for the fact that two different folks in the Series 3 customer service area have made these promises then never followed through with them. As such, they are utterly useless to me. I'm not starting a class action suit on my own against Knology and I'm not strapping dynamite to my chest and heading over to their office in order to force them to do something they have thus far utterly refused to do. Well, I'm probably not going to do that, mainly because I don't know anywhere to buy a reliable dynamite device. Also, I saw what happened to Arzst in that episode of Lost, and it didn't look like fun. So, I am caught in the middle of customer support hell, trying to figure out which one of them is in the wrong (both of them have behaved abominably thus far, of course) and which one is most likely to come up with a functional solution. Meanwhile, I've got an $800 paperweight that gets less channels than my Series 2 units do when hooked up to the same television. This brings me to you folks. I am on a fact finding mission here. I know from casually visiting these boards over the past year that sometimes cable card misadventures occur. Is Knology right that some cards, specifically the Scientific Atlanta ones, will not work? TiVo is saying that there are only two brands of cable cards and both work, but if this is true, Knology sure doesn't have a clue how to make it happen. Also, is TiVo right that Knology is legally required to provide functional cable cards to me, the customer? That seems likely, but I have no idea how to proceed in forcing them to behave properly on the matter. If you have had a situation similar to this or have discussed such a scenario with someone who has, what was the problem solving technique utilized to facilitate the process? Thanks in advance. I'm a day or two away from just returning the TiVo, but that feels like it would be letting Knology's incompetence win out.
