    You are currently running the same firmware release as I am. I have had to set my Roamio to 5 active tuners to have a completely error free viewing experience. This is a temporary fix while I wait for Charter Cable to make the PKEY1.5.3_F.p.1101 firmware available to it's customers.

    Have you tried changing the number of active tuners on your Roamio to see if the problem goes away?

    Go to Settings > Channels > Channel List
    Enter one of the following number sequences using the number buttons on the remote.
    (you will here a sound similar to when you press the "Thumbs Up" button once the code is entered properly).

    These codes will tell Roamio the how many tuners it can use.
    - 88633 = use 3 tuners
    - 88634 = use 4 tuners
    - 88635 = use 5 tuners
    - 88636 = use 6 tuners
    Then force a reboot of the Tivo, very important! Do not skip this last step!

    I changed mine to 4 tuners for about a week and found that my Roamio worked without error. I then read on this forum that 5 tuners might also work. I switched to 5 active tuners and have been running with that setting for about two months now with ZERO problems on my Roamio.

    I have a Roamio Pro, three Tivo Mini's and a Basic Roamio 4-tuner all connected via MoCA networking... (The Basic Roamio (4 tuners) has worked perfectly from day one with an even older firmware release, PKEY1.5.2_F.p.1601), pointing further to this being a greater than 4 tuners problem. The fact that I have two active CableCards from Charter at different firmware release levels leads me to think Charter has a problem updating firmware over the cable....

    Reducing the active tuners is not he ultimate solution, but it works for now. There have been very few times where I could use the 6th active tuner, so it has not been a big inconvenience so far, but I would like to have the full functionality that I paid for in my Tivo.

    I forgot to mention that the main problem I was having with my Roamio Pro was seemingly random V58 Unauthorized channel errors

    I second this. Anyone having any problems getting channels while using a Cisco (aka Scientific Atlanta) cablecard with an older firmware should try switching to 5 tuners (and then rebooting!) to see if it solves the problem. If that doesn't help, try 4 tuners. (Although 5 seems to work for most people, there seem to be some circumstances where dropping down to 4 might be needed.)

    My Roamio works great as long as I have it set to use only 5 tuners. Sure, I look forward to the day they roll out 1.5.3_F.p.1101, but I'm not exactly holding my breath while I wait. (The last time Charter sent out a cablecard firmware update in my area was 4 or 5 years ago, after all.)

    Try removing the splitter and using the most direct connection you can. I had similar issues with a 2way split feeding a 4way that feed the Roamio. I removed the 4way and the issues went away.

    From a technical aspect, the higher the S/N ratio is the better. Noise is bad.
    From a signal strength point of view, if the cable company is over amping the cable (resulting is a high signal strength), their amps could be clipping, and introducing all sorts of issues. On analog, over amping the signal would result in images of certain channels appearing on other channels (harmonics). Introducing a splitter or attenuator at your house drops the hot signal, and the resultant harmonics. Its the harmonics that are causing the problems. If Tivo picks that up as "noise" in their S/N ratio reading, then that would explain why they say the S/N should be lower. Its really not noise that its reading though, apparently.

    The comcast tech that comes out should be able to drop the hot signal down to where it is supposed to be, on the pole/amp. Make sure you tell them that you think the signal is overloading your tuner.

    Hope you get it all worked out.

    So not literally every single channel.

    This means that your cable card is not PAIRED correctly.

    More likely that it is not authorized for the correct package.

    Comcast showed up today with their… "one more thing"

    they made me a part of their beta test group for the 1.5.3. fp1101

    They updated my cable card to work on this firmware and boom problems solved.

    No attenuator nothing.

    I have all 6 tuners and so far… knocking on wood all working channels.

    they will be checking with me regularly for progress reports on any problems with the box.

    Seems problem was totally cable card related.

    we'll see if everything stays working from here on out with the new firmware.

    It is unlikely your problem was firmware. As part of the firmware update, they had to re-pair yet again and probably also checked all the settings on your account again and you had the attention of non-clueless people this time around.

    Based on all I have read, I believe your problems all along were simply they were not pairing and setting it up correctly due to repeated gross incompetence.

    It was the firmware. No doubt in my mind. Especially, in my case, after having 6-8 different cable cards, 10-12 tech visits, and at least 20 re-pairings -- first with a Premiere and then the Roamio. 1.5.2. 2401 (from 1401?) fixed the daily to monthly rep-pairing, and 1.5.3. 1101 fixed everything else.

    Thanks :up: for providing this information, both the problems and the solution. I live in Huntsville, AL and plan on using Comcast & TiVo. We are not too far from Memphis so if this problem affects both our areas I will be knowledgeable and armed with the solution!

    Excellent! No need to switch fewer active tuners then!! :up:

    Now if Charter would just get on the Firmware Upgrade Ball...

    After so many attempts for a cable card firmware update using regular channels, I finally yesterday emailed To : comcastcares_support@comcast.com with details. Today I received a call, 30 minutes later my cable card was updated to firmware 1.5.3 1101. I have reset my tivo to 6 tuners and so far, ok... :) They say they are pushing out the update in waves in my region, westminster, md, but scheduled mine special today.

    Been fighting this issue for a few days as well. Used the above email address this morning and within 2 hours received a call from Comcast apologizing and submitting my serial numbers to engineering to get the firmware pushed in the next 2 days. Seems like this team is well aware of the Roamio issues and knows how to get them addressed.

    What information did you include in your email to Comcast? I'm still trying to get the right person to read mine.
