    So when TWC said the CC was authorized they weren't lying, they were just ignorant to everything else that needed to be in line. The problem was that the HostID and some other information was still in the system from the original CC tied to my TiVo that died. I think the tech said it was "Authorized but not paired". Then we went through a ton of the CC and TA diagnostic menus and the guy at the TWC NCCS place made a bunch of adjustments to stuff.

    It got me up and running so I am happy.

    FWIW: The TWC whole home DVR is NOT anywhere near as good as the DirecTV offering. I could write a book about all the problems with it. Remote playback is fine, but everything else is ridiculously bad.

    The problem with missed recordings on SDV channels was not fixed by the latest software upgrade for the Premiere series. I realize this is a Series 3 area, but since that software wasn't upgraded, I didn't think anyone expected the problem to be resolved on the Series 3. It hasn't been solved on the Series 4 and in fact, the problem has got worse because the new software misses recording on non-SDV shows too. It's happened to me on a Fox primetime program and an ABC primetime program in addition to the regular "the video was not available" for a SDV recordings that pops up regularly.

    I wish that this could be fixed. It's the most persistent bug.

    I wish the running out of guide data bug could be fixed too.

    This is related to the insertion of the Tuning Adapter (Time Warner/Torrance.)
    Problem started last July 2011, weeks after t/a had to be put on line at the end of June 2011.

    I have never had the running out of guide data bug in my 2 years with a TV on either a S3 or Premiere.

    I used to miss more recordings than I do now - but never more than 2-3/week (maximum!). Now I only missed maybe 1 a week due to missed TA tunes. Usually I just have a few stubborn channels.

    While it still pisses me off that it's still an issue at all, I suspect that's the reason it's so hard to fix... because there are a million different setup issues that can make the problem better or worse.

    In a perfect world, the cable companies would actually CARE and attempt to fix the problems themselves... since TiVo can't be expected to have insight into each users' setup.

    Ive seen the issue on my S3 (only), but in my case, the message was false... the guide data was there. A reboot eliminated the message.

    The TA tune issue is the biggest hitter for me... on all of my boxes, S3, THD and Premiere.

    TiVo Suggestions still dont work on the S3 due to the TA.... but I can live with that if I have to... but the TA tune is maddening.

    Oh, and on the TA tune issue, Ive noticed something on it. Ive caught it red handed a couple times... and if I go into TA diags, the 'retries' value in the 'bad' session is always nonzero... So it looks like the TA is retrying the tune but it and the TiVo are not on the same page as to this retry.

    In addition to the guide data problem; in the first month I would get channel not available(?) or something like that message.

    Time Warner replaced the home drop from the pole and that problem, knock on wood, is fixed. Seems a rodent had chewed the RG6 cable up at the pole.

    I was goofing around with one of my Premiers last night, and I got a message saying it could not tune the channel. In this case it was 1114 (TWC News 14 Carolina). 1115 (NY1 HD) also would not tune, so I flipped through all the HD channels to which I am subscribed. All but those 2 would tune just fine, so I did the same thing on my Cisco 8742HDC and got the same result for those 2 channels (channel unavailable at this time). I wonder how many other TA "failures" are just systemic problems and not TA/Cable Card problems.

    I know that for my 'TA tune failures', they arent general/consistent issues. I have two TiVo's recording exactly the same schedule. When i get the issue, one will tune and record successfully and the other wont. This is really the only problem I see... other than this, everything works pretty well.

    I have both Tivo Premiers with tuning adapters and TWC Whole House DVR (utilizing MoCA) service in my house. Currently, I have the Tivos and WHDVR in separate rooms, and there is a filter between the WHDVR setup and the rest of the cable jacks.

    My question is: If I want both Tivo and WHDVR connected to the same TVs in the same rooms, can I do that with a single cable jack per room? I am thinking all I need is a splitter at each jack and some additional MoCA filters. Is there any reason the MoCA network and/or filters would interfere with the operation of the Tivos, CableCards, TAs, etc.?

    Thanks,
    Ted

    From just a few minutes googling about filters it appears that the only place you need one is at the point of entry for the cable... ie where it enters your house. The filter keeps 'your' moca stuff from going to the neighbors.

    TiVo shouldnt care about the higher frequencies >860Mhz but if it somehow was upset by them, you could use a filter there to eliminate them. The splitter you use though would appear to have to be suitable for high frequency >1.5Ghz.

    Im sure there is someone more knowledgable then me out here on this subject.

    Sounds good. Do you know what frequencies the TA uses to talk upstream? They did put a filter on my DOCSIS 3 modem, so I assume that is somehow affected.

    Both of my tuning adapters have needed power cycling in the past 24 hours. They have been operation less than a week. Is this normal? Maybe a firmware upgrade?

    Both of mine crapped out sometime last Friday. Neither were blinking strangely and all status in the TiVo diagnostics appeared normal, I just wasn't able to tune any channels until I power cycled them.

    I think this happens at least once a year for firmware upgrades.

    My Premiers both noticed whatever problem occurred and displayed a message that the TA had been removed. After the TA power cycle, everything was back to normal. Once a year is not bad, although it would be nice if they could tell us it was coming.

    I got a mail notice from TW that the SDV channels are going to be changing. I think this may help a lot of people because I don't watch most of the new switched channels. Curious that Fox News is going to switched now. Apparently Fox News is one of the "less watched" channels in Central Texas. Hmmm? Most of it seems to be standard def stuff moving over to SDV. So, I'm hoping the major HD channels are not going to be switched and that will make recordings a lot more reliable. Switch supposed to take place June 23. Will they upgrade the Tuning Adapter firmware? There is some lawsuit between Cisco and Tivo over patents. Can't be good.

    Also the local HD channels are not going SDV. Anything on the list will go SDV unless last minute changes are made in which some of the channels are not switched. I know that TWC was going to make ZEE TV and TV Aisa SDV in North Texas but that did not happen.

    I actually asked about this in the other Time Warner Cable thread to see if people in Austin were getting a notice about more channels going SDV. I don't think the changes will happen before June 26th though which is when TWC is moving KXAN HD and KNVA HD on QAM to to a new QAM channel according to their legal notices. Also TWC does not usually make changes that are major like this on a weekend which june 23rd falls on.

    Curious what are all the channels going SDV?

    I know that the Dallas cluster is having KXTX HD moved on June 21st to a new frequency which I am assuming is 153MHz (RF19) as that channel has a QAM on it now. I am assuming that north texas is having 2 more VOD carriers added.

    We had a lot of channels in North Texas moved to SDV last october which almost all of the digital SD channels went SDV and TWC added 8 more SDV frequencies for total of 24 up from 16.

    I am going to assume that TWC is adding more SDV frequencies in Austin too! Probably 8 as well. I am going to assume that this should help with bandwidth congestion on SDV channels being blocked. I know that when TWC did this change in North Texas which is a 860MHz system compared to austin/central texas being at 750MHz which means you guys have less bandwidth and they are having to squeeze more in with less space I believe that Austin only goes out to 771MHz as the highest channel while Dallas goes out to 861MHz as the highest channel.

    That is not at all surprising, for several reasons.

    It really doesn't make all that much difference. With SDV, the primary channel limitation is not the overall bandwidth, it is the number of receivers per node.

    There is a common misconception concerning what constitutes "less watched". The primary feeds of the big 5 national networks garner better than 80% of the viewing share, leaving 20% to divide up between the other 150 or so channels. A linear QAM modulator like those from Big Band transmit 8 QAMs. With industry norm rate shaping, each QAM supports 11 SD videos, 1 HD video and 6 SD videos, or 2 HD videos and 1SD video. If the CATV company has 3 fixed QAM modulators at each hubsite, they could deliver the top 40 HD channels and the top 64 SD channels as linear, with the rest being SDV. The question then becomes, "Will the savings incurred by buying another fixed QAM modulator at the headend rather than SDV equipment be offset by the number of channels that cannot benefit from SDV?" If a channel's market share is high enough to more or less guarantee at least one subscriber's receiver is going to be tuned to that channel on every node in town for a significant part of the day, then no benefit is gained by putting the channel on SDV.

    A typical CATV company may have between 400 and 1000 homes passed per node. If we assume a 70% penetration and an average of 4 receivers per home, that amounts to between 1120 and 2800 receivers. Let's assume the number is 2000 for a round number. That means any channel whose penetration is near or below 0.05% stands a very good chance of not being watched on a particular node. That may sound small, but consider after taking the big 5 plus HBO, ShowTime, and the next 33 most popular channels off the list, the most watched of the remaining 120 or so channels will each have at the very most a .06% market share, with the vast majority falling well below .01%. "Less watched" does not only mean the Japanese Knitting Channel. It means just about all the "2" channels (CNN2, ESPN2, etc.), most of the news channels (including Fox News), and all the auxiliary movie channels.

    'Also not surprising, since a single QAM carrier frequency across all the nodes in town can potentially deliver hundreds, possibly even thousands of SD channels. The limitation is the number of unique SD channels per node that must be delivered. If there is a peak of about 80 unique SD SDV channels being watched per node, then they need to allocate 8 QAMs, or 48 MHz of bandwidth to deliver all the SD SDV channels being offered.

    It shouldn't. If you are getting any denials, then their CATV plant is improperly engineered. In a properly engineered plant, any individual customer should not see more than one or two denials at most per year.

    It's unlikely to impact anything in that vein. The CATV systems forced the equipment vendors to implement the TA to keep the FCC and the CE manufacturers off their backs. The CATV companies couldn't care less whether Cisco is suing TiVo or not, and it is the CATV companies that are the CATV equipment manufacturer's customers, not TiVo or TiVo owners.
