Tivo is blaming V53 error on SNR ratio?

    I'm using frontier fios in WA. I had a constant 41dB on my SNR range (solid 100% signal). I put in the POE Filter for MoCA along with a 20dB attenuator which dropped my levels to 90% signal and 35dB for SNR, so far I havent seen any Macro noise on my tv, i'd used to see them every so often even after getting the updated cable card. Hope this helps

    Hi barrett14 I agree with CrispyCritter and just wanted to share my experience to give you a perspective. My experience shows me that SNR 37 is not too high but I may be wrong. The Roamio tuner is definitely different and that is why I shared about having one on a long run that is still getting a strong signal.
    When I had troubles with my former provider the only solution I had was to switch providers. If I lived 2 blocks north of where I live I wouldn't be able to do that because my present provider doesn't offer service that far north. So I got lucky. But I think you would waste your time with complaining to Tivo.
    Sorry not to have a solution just wanted to say that I am finding SNR 37+ doesn't give me the same problems you are experiencing.

    If I am getting error V53 on my Premiere-4, but not on my Mini (same channel, same moment in time), does that suggest anything?

    It made me wonder about my whole-house Moca adapter, but not exactly sure how/why/if that plays into anything. I know that Moca runs at 1.15ghz and I only have a 1ghz splitter. I was told by Tivo tech support that is okay, but maybe not.

    I'll go check out my SNRs. Is that by tuner?

    I don't get the V53 often, but boy is it annoying. I have become so dependent on that live buffer, I can hardly watch tv without it.

    Moca should be independent of an overpowered SNR causing V53, so that doesn't need to be worried about here. SNR would cause problems only within the tuners on your Premiere.

    If you have overpowered signal problems, then having two tuners on the Premiere tuned to the same channel (one being sent to your Mini, one for viewing on the Premiere) could very easily cause more problems. Those problems could show up as V53 errors on either or both tuners.

    SNR is by tuner within the DVR Diagnostics menu (found by a couple of paths; I tend to use the one System Information.)

    That is interesting... its very possible - my viewing habits are strongly biased to ABC. I will check that out.

    All my SNRs between 35-37. All my signal strengths were 88-91. Both stats are mostly fluctuating all the time... that was surprising (to me).

    V53 channel and non-v53 channels seemed nearly identical. I would prefer all those screens in a nice spreadsheet side by side :). Hard to compare in scroll-down fashion to state that precisely.

    I'm having 'channel not available' issues and it has nothing to do with Tivo since I'm getting it in the bedroom where we still have a Time Warner DVR. They sent a contractor tech out and he said he had plenty of previous work experience with cable and TW. He said that cable and other hardware behind boxes can go bad after just a few years, or that a lightning strike can affect the whole block. Groups of channels can drop out at random times, showing 'not available', and that's what we've experienced in the bedroom on multiple TW DRV's, while we've had no issues in the den, where the cabling has been updated and 'balanced'. Our cable run from the den to the bedroom likely needs to be replaced.

    The tech said we need a TW tech and their fancy, expensive meter (which his co. doesn't have) to check our system. From what he said, they have the ability to find problems even if you're not getting any 'channel not available' issues at the time.

    I know when we had the den area upgraded that there was no problem needed to spot the outdated cabling and splitters, since the problem I called them in for turned out to be my wireless router.

    I have Charter in Northeast Georgia and my dual-tuner Premiere started throwing V53 errors about two weeks ago. My new Roamio plus arrived yesterday; I'll set it up tonight and report if the problems get better or worse.

    Surprisingly enough, I griped on twitter about the error coming up during MNF and posted a picture of a frozen Aaron Rodgers, then got an @mention from the @Charter account a day or so later. Could it be that that account is being resurrected?

    New(ish) Roamio, Comcast is the service provider.

    I reported an evening of Error 53 activity to the forums.tivo.com. Two weeks later, I received a reply which struck me as being a bit of a wild guess.

    That is, as I reported my S/N as being 39-40 as part of the "this is what was happening when" description. The first thing I was told was that "that's too high a S/N, it should be 36 and error 53 is related to the cable card".

    I replied and explained the six tuners are all over the map with S/N and with a 6db attenuator slapped onto the line, a couple of the tuners dropped, and a couple stayed the same. I asked him how to specifically reduced S/N and received nothing in reply.

    Comcast brought a new X1 DVR when they set up my service, not knowing I was a Tivo user. So he set things up and used the diagnostics on the X1 - which was fine as it's their damn network and if it works for their box, it should work on the Tivo. He tweaked my feed to be 37db, which he said was optimum for their X1, and it was reflected on the unit's diagnostic screen.

    My Roamio, as I said, showed 39-40 on the same feed.

    I think the disparity is causing some confusion and thrashing about.

    I reseated my cable card, rebooted and haven't seen the issue again. I have left the 6db attenuator in place and will not remove it until I start seeing issues.

    I would really like a formal statement from Tivo on this. I speculate the reported S/N is like an idiot light on the dash of your car....it indicates a pulse but little else.

    I been looking at these forums for a while now and I can honestly say that Tivo has dropped the ball on there newest DVR. I have been super critical about Tivo given this is their 5th generation box and should know by now everybody who calls up is not wrong or be to quick to dismiss something because it does not fit in to the steps for what could be wrong according to their troubleshooting script.

    I spent over two weeks trying to convince their own Tech support that the problem resided on their end and not mine. It was only after I jumped through all of their hoops did they agree that Yes indeed it was on their side and I was missing part of the Tivo software. The thing that pissed me off was the fact I told them I have miss-matching settings on both of the Roamio's I owned and I was told I didn't know what I was talking about. So stick with your fight until you get your problem fixed.

    I call BS on the SNR threshold the CSRs so quickly jump on. My SNR readings are 42 or higher on all 6 tuners with signal strengths pegged at 100 most of the time and I haven't had tuning issues with my Roamio Pro.

    I second your BS, and raise you a horse-patty. Having more actual signal than noise (SNR) "should" always be a good thing. In tivo's case, who the hell knows?

    I can reproduce V53 by doing this:

    1. Set up 6 recordings on different channels at the same time.
    2. In the middle of the 6 recordings, reset the TiVo.
    3. When the TiVo comes back and continues the recordings, I get V53 on one of the channels.

    Same result if the CableCard is reset (by the cable company?). I have not encountered V53 other than these two cases. My SNRs are 39-41. I just bought an attenuator and will repeat the test when I get the chance.

    I have charter and get the channels not available too. In my area it's Charter's fault. They're trying to move channels up to achieve all digital and 150 HD channels in all areas. I suspect that and occasional odd problems with the head end. One time the low end channel was available while the HD wasn't. PIA trying to get someone to talk to my head end through the call center.

    Do you have a signal booster? If not see if you can get the tech to install one for you, it may help and then again, it may not, but at least you'll rule out other problems. It helped with picture quality when they did our new install after coming back from Directv.

    I am having the same issue with Roamio who freezes. The signal attenuation seems to work. But then no more internet on the box when having an attenuator on the line. I would like try your "mburnno " solution of having TiVo installed the missing software on my Roamio.

    Please provide us with the steps on how to have TiVo add that software. And what software should we ask for.

    Folks this has NOTHING to do with high SNR levels, period. TiVo is well aware of the V53 errors and last I heard they are suggesting it is a problem with Tuning Adapters and are working with both Motorola and Cisco to get it corrected. I only experience these errors on SDV channels. I have to reset my TA at least once/week to correct this issue and it's VERY frustrating. TiVo assures me that this will get fixed, whether or not is does - only time will tell...

    Right huh?! Who designs any electronic device where something "better" is actually worse?!

    If they are trying to justify having too hot of a signal....then just put in an actual signal level, not this percentage crap.

    And really....when you can plug in your cable companies box into the line your Tivo is on...and the cable guy tells you everything is perfect, how can Tivo then blame your setup?!?

    What I find interesting is that so far no one has been able to narrow down why some people are having these issues....where others (like me with high signals and SNRs) aren't.

    It could very well be that error V53 is generated by many causes. IF anyone knows anything about programming, this basic error handling algorithm may explain V53 with a diversity of root causes:

    IF problem-a
    ........generate V1 error
    ELSE if problem-b
    ........generate V2 error
    ELSE if problem-c
    ........generate V3 error
    ELSE if problem-d
    ........generate V4 error
    ........generate V53 error // the catchall error!!!

    I don't have a tuning adapter, and I also get the V53 error.

    Any chance this error is related to the cablecard firmware? I have a SA/Cisco card running a firmware version from 2007 which doesn't work with 6 tuners. So I am dialed down to 4 tuners for now.

    I too an having V-58 errors. I am on Charter Cable in East Tennessee. I spent at least six or seven hours with various tech personnel trying to resolve this problem. Tivo tech support thinks it's a tuning adaptor firmware problem.
