    That's not possible. The card can not decrypt the channels unless it's paired. That's how the CableCARD spec works. So either your card is paired or the channels aren't encrypted.

    Save yourself the trouble and just get a replacement cablecard. Most likely they just haven't removed the old pairing. Comcast provides cablecards as self-install kits. If your local Comcast won't, you may have to contact corporate to get the ball rolling.

    OK I researched this a bit and we're both wrong. There are two levels of "encryption" when it comes to CableCARDs. The first is conditional access, where the card simply needs to be linked to your account to authorize you to access the channels you subscribe to. The second is actual encryption and requires the card to be paired to a device to decrypt the channel. However neither one has anything to do with "copy protection". Copy protection is handled by the CCI byte and can be set regardless of the "encryption" level used.

    So apparently in your specific area they use conditional access, but only use the higher level of encryption for premium channels. In my area they use the higher level encryption for everything except locals and a few basic cable channels. So if the card is not paired you can only access like a dozen channels. However they only copy protect premiums because all other channels can still be transferred between TiVos and to a PC using TiVoToGo.

    I can used and sometimes do use a non paired Comcast Moto card in a TiVo and get all stations except the HBO type stations. Comcast encrypts ALL stations now in my area, my new HDTV can't now tune any cable station with the built in tuner, I assume OTA would work.

    Read my post above. There are two ways to setup encryption. One requires pairing to a device, one just requires the card to be registered with the account. However neither is explicitly linked to copy protection, which was the point of my original post. Copy protection is something completely different. You can require pairing, as they do in my area, without protecting every channel.

    How am I wrong? It was your claim that you cannot decrypt anything unless the CableCARD is is paired to which I objected. I never even mentioned "copy protection". I am quite well aware that copy protection is controlled by the value of the CCI byte and has nothing to do with encryption.

    I thought you were the same guy I replied to initially who claimed that only "copy protected" channels require pairing. Although you were quoting my reply to him in your original rebuttal.

    In any case my original post about pairing having no relation to "copy protection" is still true.

    Just got this email from Comcast which sort of applies to some of the discussion here:
    Important Service Message:

    ***Deleted*** see repaginated post below this one. Much easier to read. Thanks SullyND

    Is Comcast Haiku?

    Repaginated so that it is legible.

    Important Service Message:
    On March 6, 2014, Comcast will start encrypting Limited Basic service on your cable system.

    If you have a set-top box, digital transport adapter (DTA), or a retail CableCARD TM device connected to each of your TVs, you will be unaffected by this change. However, if you are currently receiving Comcast's Limited Basic service on any TV without equipment supplied by Comcast, you will lose the ability to view any channels on that TV.

    If you are affected, you should contact Comcast at 855-860-8989 to arrange for the equipment you need to continue receiving your services. In such case, you are entitled to receive equipment at no additional charge or service fee for a limited period of time. The number and type of devices you are entitled to receive, and for how long, will vary depending on your situation:

    - If you are a Limited Basic customer and receive the service on your TV without Comcast supplied equipment, you are entitled to up to two devices for two years (five years if you also receive Medicaid).

    - If you subscribe to a higher level of service and receive Limited Basic service on a secondary TV without Comcast-supplied equipment, you are entitled to one device for one year. You can learn more about this equipment offer and eligibility at comcast.com/digitaladapterinfo or by calling 855-860-8989.
    To qualify for any equipment at no additional charge or service fee, you must request your equipment between now and July 4, 2014 and satisfy all other eligibility requirements.

    They did this in Minneapolis/St. Paul (well, at least my suburb with a Motorola head-end) last year. The local cable authority got a lot of negative feedback, which they funneled to Comcast.

    I may have confused things by using the wrong terminology. Sorry for that. My point was that on my cable system (Comcast/Motorola) I can receive all channels except the premium channels with an activated but unpaired CableCard. I think this is the same for Comcast/Cisco cable systems. Since the OP was only recieving a few broadcast channels, I figured his problem wasn't CableCard pairing.

    Can the OP please state what part of the country you are in so that we can possibly see if any other Comcast customers from that region can chip into this dialog with their own experiences?

    Based on all the limited info presented thus far, I'm beginning to lean to the possibility of a bad box as opposed to a bad CC, given that the OP claims to have used more than one CC in his Roamio thus far (I think that's the case, although the story is beginning to get a bit garbled)...

    So is Comcast going to start encrypting the locals around the entire country? I wonder when the other major cable providers will start doing this?

    Yes, and when they realize they can make people have to pay for extra outlets they are getting free now...after the legally mandated "free period".

    I'm in Memphis, TN.

    I agree if you guys are correct about this firmware not being the issue, then I think I may have a bad box too.

    I have used several different cable cards in this box with the same result.

    Have you checked your Tivo cablecard status screen against the correct readouts: http://support.tivo.com/app/answers/detail/a_id/2571

    If you post what is different about your readings vs what they are supposed to be, we might be able to figure out what the problem is.

    I had a similar situation!

    ... And this solved it for me.

    Over the last few years, my living room TiVo has gone from a Premiere to a Premiere XL4, a Roamio Pro that died after 3 days, and then the current Roamio Pro.

    Each time I changed TiVos, I only changed the TiVo. The cable card and the wiring (hdmi, power, USB tuning adapter) stayed the same.

    Couldn't get the first Roamio to work with the cable card. Cox said it showed paired on their end, but I couldn't get any encrypted channels (which seem to only be HBO, etc in this market). The TiVo died before this was solved, so I was hopeful the replacement TiVo wouldn't have this issue.

    No luck. Roamio #2 acted the same. Cox showed paired on their end, but I got no encrypted channels on my end.

    Talking with TiVo, they noticed the SNR was super high. They suggested an attenuator. I had a 4-way splitter, so I used that instead. That dropped the SNR level. I called Cox. They unpaired/repaired the cable, and everything has been fine since then.

    Weird that the Roamio choked on the same cable card/wiring/signal that two models of Premieres had no problems with!

    I have seen reports here, but haven't seen them substantiated by looking at the hardware, that the Roamio has an extra internal amplifier because of the 6-way split. This seems consistent with various reports like this one and other reports that there are occasionally more problems when multiple tuners are on the same channel (eg after reboot). Has someone verify this on the hardware?
