    So I guess it's safe to assume that you still haven't fixed the bug that keeps the TiVoHD from reliably recording?....

    Thanks Jerry, I appreciate that and am glad I could help. I also have to say that the guys I worked with at TWC were awesome. They spent a lot of time and effort on this one and delivered the goods. They taught me a lot too for which I am grateful. And of course... thanks for fixing it!! :D

    I'm glad they fixed the very technical bug that caused picture breakups. I'm worried that the more severe bug: blank recordings on SDV channels on occasion may still be unresolved. I'd rather have an actual recording with the breakups than nothing at all. I of course appreciate the fix to the picture break-ups and the effort and dedication it took to fix it.

    How exactly should Tivo approach fixing the problem of blank recordings? In earlier posts, I suggested some kind of error condition testing and that the Tivo could do automatically what users have done to correct the problem, i.e., changing up then down to re-tune the desired station.

    Since you suggested the precise method of addressing the very technical bug, what exactly is the best approach in fixing the tuning issues with SDV channels? Seems like this is the very last issue with Tuning Adapters to be addressed.

    SCSIRAID or TivoJerry do you have any answers? How do we get this bug fixed? I used to feel pretty confident my Tivo would never miss a recording. However, it's about 75% reliable generally and under 50/50 if you record two SDV channels at the same time.

    The TiVo seems to know when a channel isn't tuned, i.e., has blank video. The failed recording shows up in the Recording History as not recorded because the video signal was not present. If nothing else, why not have the TiVo do the same thing you do manually to work around this, i.e., tune up 2 channels then back down ? It should try this at least twice, based on my experiences doing it manually. I suspect there might be a more direct way of re-tuning than channel-up/down but.....whatever works.

    I will mention that being somewhat new to Tivo - the cable company DVRs do the same damn thing. It blows my mind. I know whenever I am writing code and try to get access to something, if I can't I wait a few ms and try again...

    I guess since I'm apparently not running into the problem, I'm just curious... I don't remember reading about this problem. Just to clarify, you do mean something separate from the "blank analog channel" problem, right? (I'm just trying to make absolutely sure whether you're using SDV to mean "digital but not HD", or "any non-HD, including analog").

    I've complained ad nauseam in the past about the "joys" of outsourcing engineering to places like India. Do you really think that Apu in Bangalore really gives a s*** about the quality of the code he delivers? I don't. He'll never have the opportunity to use this product at his home. It's just a black box computer to him.

    If it comes somewhat close to meeting the customer's spec ---> "ship it". Going the extra mile to "wait a few ms and try again" just isn't part of the equation.

    I have no idea of whether this particular code was outsourced. One would hope that direct company employees would have a little better pride of ownership. Plus by being physically present in the same hemisphere it might be easier for testers at TiVo to make suggestions for improvements.

    It's a problem tuning SDV channels and has been mentioned in posts many times. **Here** is a TiVo support page that discusses the manual workaround where you find:

    It only happens on SDV channels and I lose one or two recordings a week due to this problem.

    I experienced this very serious problem when I got my TA from Cablevision. It rendered the TiVo totally unreliable. My options were to leave the TA disconnected or cross my fingers and hope for the best.

    I even had Cablevision come out and try to help troubleshoot, but the tech even complained that he had no training on how it worked.

    It was the last straw I had trying to get TiVo and Cablevision to work nicely together. I finally switched to Fios (which is not an option for many) because it eliminated SDV.

    I will mention that since getting an return path amplifier, this does not happen to me anymore.

    I got this guy:
    http://www.yourbroadbandstore.com/product.php?pid=716497

    If your return path level on the TA is pegged at max (like ~54db) then I would suggest trying one.

    And where exactly in the coax chain is this thing installed?

    Do you have multiple TAs (and multiple return path amplifiers), or can one amp handle all TAs from the demarc, e.g., can this be installed at the main entry point for the coax?

    If not, does it go between the (each) tuning adapter and Tivo, or between the (each) TA and the wall outlet?

    Since this is a solution that worked for you, add some more information so others can duplicate.

    That sounds like the TA simply stops talking to the headend so the headend thinks no one is watching the channel and shuts it off. Switching the channels back and forth triggers the TiVo to tell the TA to tune the channel again.

    That sounds like a disconnect somewhere in the TiVo to TA communication. What's supposed to happen when the TiVo goes to record something is that the TiVo tells the TA it wants to tune channel X for a recording. TA tells the headend which "turns on" the channel on a specific frequency and tells the TA. The TA then tells the TiVo which tunes the channel on the frequency.

    Periodically the headend will ask the TA if the channel is still needed. The TA should ask the TiVo. If there's no recording in progress, then the TiVo should put up a "are you still watching" prompt. If there is a recording, then the TiVo should reply to the TA that it's still recording. The TA should then tell the headend that the channel is still being used. Some part of that mechanism is broken so the headend simply turns the channel off (hence the grey/black screen). It could be a headend, TA or TiVo problem. Since this appears to not affect the majority of TA users, my guess is that it is either a headend or TA problem.

    But this happens when you first try to tune a channel.....

    (Or when TiVo first tries to tune it to start a recording.)

    It could be as simple as a timeout that needs to be increased in either the TiVo or TA software interface.

    When you have a recording loss... do you also have an entry in the recording log stating that it wasnt recorded because the 'video signal was not available'? I see those too but not to the degree that you mention. The downstairs TiVo records a lot of the same shows as my upstairs one. I have found situations where the show DID record on one TiVo but not on the other. This says that its not a lack of SDV slots since it should impact both TiVo's. Ive also caught it redhanded (recording in progress with black screen) and found that several of the 'lock' items in DVR Diags that should have been 'YES' are 'NO' which strongly suggests that its a tuning problem. Now whether the TA gave TiVo bad info or TiVo failed in its tuning of the program... I dont know. If TiVo wants to loan me a USB analyzer, I will gladly birddog this one :D

    It would seem that TiVo could help the situation greatly if they would detect the 'no's' in the locks and simply time out and retune the channel.

    I could be mistaken, but I'm guessing SW version 11.0e was a Beta-test version that wasn't released to the general public.

    I agree.

    My experience matches yours. Usually the Recording History says it didn't record because no video signal was present, but I've also had it record 3 hours of blank video. I haven't looked at the lock items in such a case but I bet one or more would be not locked.

    Are you still seeing this with 11.0f ? I'm guessing it wasn't fixed.

    My THD hasnt had 11.0f long enough to really tell... and its my wife's unit and she may not have noticed. I also noticed on the generally released code that usually, a failed recording gets put back in the to do list so it eventually does get recorded if it plays again. I do my network TV stuff OTA and have never seen it OTA.

    Cool. And since i'm right down the road, this fix should work for me.
