    And don't forget that a CC and TA enabled TiVo will not record suggestions in some markets since TWC disables unattended channel changes of that nature.

    Does that problem include season pass recordings or just tivo suggestions?

    I think you will find that this is not true. The no suggestions is a TiVo S3 problem. My S3 and THD wont record suggestions with the TA attached but my Premiere records suggestions just fine with the TA attached.

    The issue with THD and S3 relative to the presence of a TA impacts only Suggestions.

    Guess I am lucky in Mason/Cincinnati Ohio. Suggestions are working fine with my S3.
    They are getting better with Blinking problem. Last month a new person on phone followed instructions and they worked. She said they now have a list of several different hits to send instead of just one or two.

    If TA cannot tune a switched channell I wonder if it is because they allocated too many channels to SDV and no free channel was available when trying to tune it. At hasn't happend to me for a while.

    Interesting. Makes you wonder if TiVo changed the type of channel change the Premiere requests or if the difference is hardware related.

    TiVo could not have changed the channel request type or it wouldnt have passed cablelabs cert.

    Im 100% confident the issue is TiVo Software. They had a very similar problem where S3/THD boxes with TA's could not 'see' S2 boxes via the network. That was fixed with the last S3/THD SW update.

    Here is a clip from my email exchange with TWC Corporate Engineering on 'background tunes'.

    Per the Channel change spec, speculative recordings are in the same class as background recordings. For example when a MDN box is buffering a channel not on the main screen that is considered a background recording. The same background time shift buffer is coming soon to ODN. Because of the amount of SDV blocks Charlotte was having awhile back I believe Charlotte and Raleigh changed the background aging setting down to 1 second.

    So what this does is, after 1 second the USRM will consider this background stream reclaimable and it can be potentially torn down if additional bandwidth is needed. I’m pretty sure this is what is going on. He is most likely in a SG that blocks on a frequent basis and because these types of recordings are best effort, and the timer is set low, it interrupts background or speculative recordings.

    Jeez, SCSIRAID, again with the acronyms! :confused: :eek:
    MDN? ODN? USRM? SG?
    Do you have cable TV experience that makes these common to you, or did you learn them from interacting with TWC engineering?

    HAHA.... sorry bout that... That came from the TWC guy... not me... I do a lot of reading and talking about this stuff so I knew what they meant though...

    MDN is Mystro Digital Navigator - the sw that runs on the older Cisco 8300HD non cablecard boxes

    ODN is OCAP Digital Navigator - the sw that runs on the cablecard based 8300HDC boxes with OCAP

    USRM is Universal Session and Resource Manager (USRM) - its part of the Cisco software stack

    SG is Service Group... its all the folks on the share the same SDV QAM pool... i.e. who you are competing with to get a channel.

    I have a Series 3 TiVo HD that I purchased back in 2007. It has an upgraded hard drive (Weaknees) also purchased in 2007. My cableco is Charter Communications (Greenville, SC). Everything was working fine until earlier this summer when TiVo stopped recording Suggestions... or only recorded one very rarely. Right now I have 329 deleted programs and only about 20 programs in Suggestions. When I review my thumbs ratings, I can see that there are *many* programs that TiVo could be recording as Suggestions. The most recently recorded Suggestion is more than a month old.

    6-8 weeks ago I called TiVo for help and they suggested I do a "clear and delete everything." Didn't fix the problem. It wasn't until today I realized that the difficulty began about the time Charter replaced my two single-stream cable card decoders with a tuning adapter (Motorola MTR700). I haven't read through the mass of posts here on tivocommunity, but I don't think the timing is a coincidence.

    And so my next step should be...???

    Many thanks.

    S3/THD's sometimes stop recording suggestions when a Tuning Adapter is installed. Both of mine exhibit this behavior. The Premiere doesnt seem to have this issue... mine is recording suggestions like crazy while my S3/THD's just 'sit there'. Hopefully TiVo will release a SW fix to address it.

    Ah... Not exactly a solution, but a helpful answer nonetheless. I've contacted TiVo so they can add me to their list of "troubled" users. ;)

    Thanks for your reply.

    My S3 has no problem recording suggestions in SW Ohio Time Warner with tuning adapter. It may be a problem with your cable company's TA implementation or if back end hardware is different then a TIVO issue.
    You could bring it up with your cable company and insist it gets to the group the implemented the TAs so it doesn't get lost.

    Question:

    My provider (Surewest Communications) is going SDV in 30 days. It looks like they will provide me with one Tuning Adaptor.. I need 3. Has anyone else been told there is only 1 per houshold? Can you get them on the market directly?

    My area just started sdv and I have lost several channels. Recieved a tuning adapter from time warner, hooked up, doesn't work. After several chats with clueless people on the phone they schedule a truck roll. Day of appointment service manager calls to get more info. Explain everything to him. Asks me brand of tuning adapter - Cisco - Tells me they sent me wrong one. Only motorola will work with my cable cards. Dont have any available for my area. Dont know when they will. So I'm SOL. Any suggestions on what to do next??

    Nothing much to do until they get the Moto TAs. You could call them and demand a rate reduction until they get you a working TA. Did you lose whole extra-cost tiers? If so, cancel them until they have working TAs and make sure that they know that's why.

    ugg..sorry to hear ATR about the wrong TA. Hard to beleive your provider would be so clueless.

    Still asking the forum for any history on getting only 1 TA from their provider, and or if they found a way to get there own.

    Charter here in West Michigan is going to SDV. Got a notice in the mail saturday and have an appointment scheduled for today. The notice said on or after August 25th I would start losing channels. Luckily it didn't happen yet. The back of the notice had the channel lineup listed but didn't specifically say which channels were moving over to SDV. Hope all goes well.

    Switched Digital Video is a new technology that allows cable providers to expand programming for the transmission of some channels to the homes of customers until the required channels. If you have Premiere, Premiere XL TiVo HD XL TiVo HD or Series 3 HD DVR CableCARDs, you see a blank screen channels if the cable service provider makes the transition to SDV.
