I'm cross-posting this in the XFinity forums, may the best forum win. TL;DR: Con: Yes, EBCP: Yes, Val: ? 0x00 I live in the SF bay area, and I've been using TiVos and CableCards since it became possible to do so. Most recently I used a TiVo Series4 XL on my housemate's account with an M-Card, worked just fine. I moved to my own place a couple of weeks ago, taking the TiVo with me. I did a self install of Xfinity TV/Internet, with my own cable modem and a CableCard I picked up at the local comcast office.* The internet works fine. I have the cable modem and the TiVo on a splitter, but otherwise the line goes straight to the utility pole. I called the friendly Eastern European people at the comcast CableCard activation line, they took down my HostID and DataID, and "sent the signal," but with no luck. We rechecked everything, I rechecked the connections, they rechecked the numbers, they "sent the signal" again, no dice. Next they sent me to the local office to get a new cable card. Same problem, but this time with "Con: No". Third card, back to "Con: Yes" but still "Val: ?" At this point we scheduled a service appointment for a tech to come out and check things out.* A week later, the tech shows up, who's super nice. Tells me the line is fine, tests all the connections, runs some line diagnostics. Everything looks fine. He calls up the activation people, they "send a signal," no change. He said he doesn't really know cable cards, and that I should call the russians again. For fun, I swap the card again, but the fourth and fifth cards are no better. Another round of calls to the russians and more signal sending. That afternoon, someone claiming to be "Comcast" calls to make sure everything is working. I told him it isn't, he "sends a signal," which doesn't work, he said his supervising tech will be calling me back to set up an appointment. This never happens. End of week one. A week later, I try doing Comcast chat support, for kicks. I talk to "Mike" who "sends a signal," asks me to reboot the box, and then we get disconnected. Chat attempt two yields "Mary" who is about to "Send a signal" but we get disconnected. Chat attempt three yields a different "Mike," who tells me he can't help me with cable cards and I should call the cable card activation line (aka the russians). I try calling the russians again, who are typically friendly, ask me for my phone number, address and name, "send a signal" but can't help. They advise me to get another cable card. Cable card six doesn't work. The russians, after*asking me for my phone number, address and name, "send a signal" which doesn't work, and they put me on hold to write a report and schedule a tech to come out. End of week two, because there are no technicians until next week. So I'm two weeks in, the internet continues to work great, and my TiVo is dead in the water. We hooked up an antenna and are using a comination of Netflix and Hulu Plus to get most of the shows we're missing, but I'm trying to figure out what the extra $25/month I'm paying for cable is getting me, aside from the ability to stream Game of Thrones on my AppleTV. Has anyone had any luck with Comcast in a situation like this? Is there some tiger team I can call who knows anything about cable cards? Is there anything they can do from their end besides "sending a signal?" Should I contact TiVo support instead? I have no reason to suspect anything wrong with the TiVO box, since it worked fine at my other house and I hand moved it to this one. The line works, because my internet screams. If six out of six cable cards are broken, then Motorola has bigger problems, but it seems like the most likeley possiblilty is something is wrong with my account provisioning. Another couple of weeks of this and I'm probably just going to ask for my money back and move to internet-only service. This is ridiculous.
