Disappointed in cable card support being discontinued

My TiVo also stopped working and they gave me a stream box, fortunately my TiVo downstairs is older and does antennae :)
I tried the stream box and its pretty much a Roku that has local and cable channels but is impossible to navigate the menu without the voice control
the remote is very feature poor cant even pause one channel while watching another and switching back and forth

also all recorded shows are online so if you internet goes down you don't have internet or tv :( before internet could be down and tv work or vice versa 
going to cancel all comcast and just get a Roku in stead if my TiVo OTA stops streaming and stop paying $15 a month for comcasts steam box and another $70-80 for the the service 
I can watch the 30-40 local channels on my antennae from my TiVo Romeo that I switch to upstairs when they decided i get the first cable card free and second one for $10 years ago
The TiVo Romeo has been good enough plus Netflix and Amazon still works on it but not all areas get antennae TV 

Sad Tivos days are numbered they have stopped making new TiVo's and they are selling their Apps/menus guides etc. to TV and cable providers 
I loved every time a cable provider called and told me about all the new features i have been using on my TiVo for over 20 years :)

Its hard to change to their menu it just doesn't make sense to me ??? all you can do is talk to it, nice but not a feature i needed or wanted 
kind of like AI i dont need it, dont want it and did not ask for it 

AI please delete your self is all I would ask :) you are probably talking to AI on your comcast remote No Thanks !

Whelp, I guess it's good bye Comcast 

I’ve used both Comcast and Ti-Vo for YEARS. Cable card stopped authorizing channels, Ti-Vo and Comcast both promised that Comcast would bring out a new Cable Card that would fix it. NOPE. Technician arrived only to say they no longer support Ti-Vo, no longer have cable cards. So I had to give up Ti-Vo. Why wasn’t Customer Service aware of this change? Why didn’t customers receive a letter or email letting us know? I feel like these are the kinds of things that make Comcast so frustrating for the customer.

Add me to the list of long-time TiVo users who suddenly lost access to HBOmax channels that I have been paying for for years. I can still get all of the basic cable channels, so my cableCard works, but it has not been authorized for HBOmax. Some of the comments in this group suggest that it is possible to get that authorization into the cableCard. Is that true?

A few months back when my promotional price ended Xfinity offered me a new promo and the agent insured me that I would not affect my Tivo cards. When the email came with my new contract the Tivo cards were missing. I quickly called Xfinity and cancelled the new promo, I am now paying full price for Internet & Cable. I have 2 Ramios and 6 Mini's all networked through Moca and from everthing I've read it doesn't look like there's any good solution when Xfinity finally pulls the plug.

It does appear like Xfinity intentionally "obsoleted" cable cards to force customers to use (and pay for) Xfinity cable boxes.  

Similar to others, I have multiple Tivo with cable cards and lifetime subscriptions which have worked perfectly fine for years. In spite of the expense ($340/mo), I've stuck with this setup because my wife is familiar with it and doesn't want it to change. Anyway...I had one of my Tivo boxes get errors and crash with the Netflix app, so I restarted the device and suddenly all cable channels stopped working (Channel not authorized, error v56). The cablecard was provided and activated by Xfinity long, long ago, and nothing changed on hardware nor my plan...I just restarted the Tivo box and now I'm paying for service that I cannot use. I spoke with support and mostly they don't know anything about Tivo/cablecards until someone finally transferred me to higher level of support who was unhelpful...basically said go get a new box and yes...we will charge you rental fee on it.

If I am forced to get a new box (and spend even more!), then I will immediately cancel cable TV service and get YoutubeTV (as well as try connecting to my HD antenna as boxes support OTA) because if Xfinity forces me to disrupt the working and perfectly capable setup which my wife is familiar with, then I will go with something that is way, way cheaper especially as we're mostly using streaming services now anyway.

If anyone can help with this, I would much appreciate it. Otherwise...I will have to break up with Xfinity.

I'm having a similar issue that started on February 3. I arrived home to find 3 boxes (2 Bolts and 1 Premiere) all with black screens and the "chennel is not authorized" error. The Xfinity CableCard activation page still showed 3 of the cards paired with the same hosts they've been with for the last 3 to 5 years. Completing the pairing process didn't change the results for the TiVo boxes.

After 2 hours in a chat and close to one hour on the phone, an Xfinity rep scheduled an service technician to visit my residence on February 6. The tech arrived and after a quick conversation about what I previously mentioned, he was on the phone with someone for about 15 minutes before saying that it was not a cable signal or hardware issue. He referred me to the store.

The store rep was incredibly nice and went through several steps before attempting to reactivate 2 of the cards of the cards associated with my account. I returned home to find my Premiere box was back online, but the other 2 boxes have not changed. Attempting another chat session now that started about an hour ago...

Mistakes in billing and updates are not accurate.
