    I checked just now; GRNHD (1051), IFCHD (1200), HMCHD (1230), and STZCHD (1370) are blank; a message from Tivo on those channels says:

    "This channel is temporarily unavailable. Press SELECT to tune to this channel again. Contact your cable provider for more information."

    Sometimes these channels come in just fine, sometimes not. The channels that drop out from time to time vary. Sometimes it's non-HD channels. Rebooting Tivo sometimes fixes it.

    Is Cox turning these channels off from time to time? Is it a bug in the SVA?

    Does anyone know why this is happening?

    I will almost guarantee all the channels you listed are SDV. Your SDV Tuning Adapter is not working properly, I'll bet the the DAVIC status is showing some other message than Connected.

    RF Statics > DAVIC: Connected, Status: Locked (This status is essential)

    Did you read the post above and check your Tuning Adapter Diagnostics?

    Thank you for that tip. I just checked again. Tuner DAVIC status is CONNECTED and status is LOCKED. My status settings look like the optimal ones posted in this thread. Just now, WEHD and IFCHD both show the message:

    "This channel is temporarily unavailable. Press SELECT to tune to this channel again. Contact your cable provider for more information."


    Using the 'Test tuning adapter channels' menu option under Settings, I can ask the Tivo to try to have the SVA tune to each channel sequentially. Many come in, but an alarming number of HD channels don't come in (black screen). This happens no matter how many times I try to tune to them. If I reboot the Tivo, the "missing" channels are still missing. If I powercycle the SVA, the "missing" channels are still missing.

    I just don't get it.

    I don't have cable (and probably never will), but I think the whole point of SDV is that the cable company doesn't have enough physical bandwidth to carry all channels at once, so they essentially overbook them by swapping lightly used channel numbers in and out of a limited number of physical slots, managed by a tuning adapter. So depending on what others in your area are viewing, there will be times when all slots are in use, and you won't be able to view the SDV channel you want until a slot opens up. The congestion may ease if your cable company moves into the 21st Century by eliminating all old analog channels.

    David, I agree, but I'm paying for a list of channels, and it seems to me I should get them all, all the time, since I'm paying for them all.

    The whole thing stinks...

    Never going to happen, there is not a limited number of slots, for SDV channels.

    The best overall summary of how SDV works was posted here by lrhorer
    http://www.tivocommunity.com/tivo-vb/showthread.php?p=8728500#post8728500

    If there is a problem with availability of a SDV channel, it is faulty equipment related, or signal issues. Either the Tuning Adapter needs replaced, or the Edge router at the node needs maintenance.

    Cox's network, as a whole, is among the most advanced in the nation among MSOs. All plants are 1GHz, DOCSIS3 bonding 8 down and 4 up are common. Cox is starting to use MPEG4. All while still supporting Analog on 50-60 channels in most markets.

    That is indeed very interesting, but he disagrees with your assertion that "there is not a limited number of slots, for SDV channels". He (lrhorer) said, "With a 100% SDV solution, the number of streams being broadcast on the node is equal to the number of unique programs being watched or recorded by the subscribers supplied by the node." And a bit later, "Moving outside of prime time, the number of unique streams being requested will go up, but the number is still nowhere near the 345 streams the node can deliver. Of course, fiber and fiber nodes cost money, and so the CATV system is going to cut the margin as thin as it can. In some cases this has historically meant some systems have had too few nodes resulting in some objectionable level of tuning denials on some of the more obscure channels." I can accept that "tuning denials" should be unlikely and infrequent in a well designed cable infrastructure, but they can happen more often than never. And in a cable system that isn't "a 100% SDV solution" they could even happen often enough to be objectionable.

    I am a Cox NoSD customer and am having the same problem in that I cannot receive certain channels from Cox. In January, I had 2 different techs come out to "fix" the problem. The first added a tuner adapter. I had been getting all channels up until the HD switch over and was told that TiVo wasn't quite ready for the change. The adapter still didn't fix the situation so a second guy came out, replaced the adapter and cable card - twice! By the time he left, all was fine, channels restored. Now I find they are gone...again. No help from Cox, they sent out a new signal but that did nothing. My TiVo is only about 4 yrs old and I don't know if a newer model would help.
