Tivo is blaming V53 error on SNR ratio?

    I forget the firmware number, but it is the one before the current version. I was told by someone in the AVS forums that the version supports 6 tuners. I'm going to try to get Comcast to update it to the latest, just to be thorough.

    The data bursts seem to occur mostly when changing channels, but I have noticed at least once getting one during a recording and the recording stopped.

    Reviewed all the comments here regarding signal interruption. Been a TiVo user since March 2009. Currently have a Premiere XL4 with a Roamio Plus on the way. If I experience the problem with the Roamio, it's going back. I'm in Arizona and on Cox cable with a TA. I started experiencing signal interruptions about a month ago. I haven't seen this problem on any recorded programs. Also, the signal loss seems to happen after I've been watching TV for two to three hours. Probably not heat build-up as the unit is on all the time. I have asked frinds, who do not have TiVo, if they have experienced this problem and none have had the problem. From what I see this is strictly a TiVo problem.

    Mark-
    The CC CP screen always means (for me, at least) that the cable card is not paired correctly with the Tivo. Based on that, I'm assuming getting a new CC should fix the problem. Everyone tells me that it sometimes takes many efforts to get a good cablecard.

    Strange thing is I have been using TiVo for five years and this problem has only started in the past two months.

    Just because the card isn't paired correctly doesn't mean it's a bad card. It means they don't know how to pair them correctly! I had the same thing with them telling me over and over that it was a bad card, including TiVo, and I insisted that I knew it was a symptom of it not being provisioned, activated and/or paired properly on their end. In the end I was correct, they finally set it up right and I'm still using the exact same card that they said was "bad" without issue.

    HarperVision is right. Pairing your existing card may also fix the problem. I figured getting a new card and having the tech talk to the office to pair it for you would be easier for you since he was already scheduled.

    Mark,

    Check your MMI screens for your CableCard as it may not be paired properly.

    I've been plagued by station not authorized errors. I seem to have gotten rid of them by setting the Roamio to only allow 4 tuners to be used. Does this mean that a firmware update of my Cisco Cable card should be done? My current cable card is version 1.5.2_F 3001, and I've been told 1.5.3 1101 is the most recent.

    I ordered the attenuator pack from SmartHome (http://www.smarthome.com/7800/Signal-Strength-Attenuator-Pads-Mix-Bag/p.aspx) and lowered my signal to 37dB. The signal strength bounces between 95-100% after using the 10dB attenuator, the signal was coming in at 42dB prior to adding it. It has only been a couple of days, but i haven't had any v53 errors since. MoCA speeds do not seem dramatically impacted, PHY rates are nearly the same after adding at 245/250ish.

    The kit was $13 shipped, and I'm willing to sell my unused 1/2 of the kit for $6 paypal shipped. You will get one each 3/6/10/20 dB attenuators.
    PM me if interested.

    Well, add an attenuation kit to my list of attempted fixes... Three months and numerous labor hours later and I still don't have a consistently working Roamio.

    This is plain and simply a TiVo issue with the Roamio line and I now have unequivocal proof after ruling EVERY single component out with the exception of the Roamio itself. I have been working directly with the head engineer of my cable company on this issue for months now. They have even loaned me their personal Roamio for testing purposes. Every square inch of my service has been checked multiple times from the pole right to my TiVo. That said, here is my proof it is a TiVo issue.

    Set up: Two TiVo Premiere's running side by side using two brand new Motorola tuning adapters with latest firmware as well as Motorola CC's also with the latest firmware. SDV channels working on both units for 3-7 days and bam, one will lose all it's SDV channels returning a V53 error. Second unit will exhibit identical behavior within a few days. Restarting/power cycling the TiVo's has no effect. The only way to restore SDV channels is to power-cycle the TA's. Now, before to say to yourself, it's the TA's failing - keep reading. If I swap the TiVo's out with the TA's without power-cycling either TA, when the TiVo's reboot - all SDV channels return until the next failure again usually 3-7 days. Keep in mind that during this time the TA's never lose sync. The head engineer believes this is either a latency issue with the TiVo's which eventually breaks the handshake between the two devices or the TiVo stops reading the carousel file on the TA itself. Power-cycling the TA or swapping the TiVo out with the other TA forces a new handshake to occur which rebuilds the connection and restores SDV channels. TiVo needs to fix this plain and simple as like many I have grown tired of the constant baby sitting my TiVo ever since my purchase...

    According to a very reliable source at TIVO you know longer have to attenuate the signal on the new Roamios. This came directly from TIVO M. The people in support have no clue when it comes to SNR.

    So how did they fix that without new hardware?
