    That's not it. I am working with the TiVo engineers and margret and they see strange issues in the logs I sent them regarding the "analog" anomaly. They are working on a solution.

    I don't think it's a conversion issue. When a problem channel appears, the banner describing the channel shows under the black screen. The banner then times out, leaving just the black screen. Also, wouldn't you hear audio in any case? (I don't know, maybe not?)

    For the record, video is set for 1080i, 1080p, and 1080p (24-fps). (Netflix now sends 1080p)

    The TV is a new 60" Vizio M601d-A3R, which should be able to handle anything thrown at it.

    That's interesting! How can we see the logs? Web interface? Hidden ssh port?

    Don't think it works on Roamio interface anymore (but haven't tried it). This works for series 4 units:
    You can inspect the Logs using Clear-Clear-Enter-Enter-0 from the System Information menu

    TiVo can collect logs from your unit for inspection themselves (I think after you give consent to do so).

    To send logs to TiVo using Roamio you hit "911 clear" then "777 clear" while you're experiencing your issues (black screen, V5x error, etc) and then connect to the TiVo service twice.

    What do you mean by "connect to the TiVo service"? Rebooting?

    Thanks for the info!

    Force a call to the TiVo service twice under network settings. The box normally connects to TiVo once a day.

    I've been able to easily duplicate the OPs problem I'm my current Roamio (4-tuner) with MoCA connected Mini setup on Bright House Networks in Tampa, FL. BHN uses Cisco TAs.

    I get very inconsistent live TV tuning on SDV channels while the connected Mini works 100%. I've rebooted the Roamio and the TA a couple of times. The problem is very consistent and repeatable. I think I will post a video to demonstrate it.

    Cox Phoenix w/ Cisco Tuning Adapter also,

    I am seeing something very similar on a Pro. Very often when tuning to a SDV channel there is just a Black screen, without the usual SDV prompt saying:

    "This channel is temporarily unavailable.
    Press SELECT to try tuning to this channel again."


    I rarely see the above prompt when a SDV channel does not display, Channel Up/Channel Down will sometimes tune the channel but not always.
    Also DVR Diagnostics lists Analog and No CableCARD Association.
    If I do get the SDV prompt, and Press SELECT, the channel will tune, but pressing the TiVo button, I lose the buffer and the buffer will reset.

    Disconnecting the TA's USB cable and reconnecting will usually solve it for a day or so, but the issue returns. I have never seen this issue on my Elite/XL4.

    The problem on my 4-tuner base Roamio has disappeared. I couldn't duplicate it yesterday.

    Is there an easy way to determine which channels are being sent as SDV on a cable network? I'm wondering if BHN changes their SDV configuration based on time-of-day.

    I am getting the same thing on my base roamio 4 tuner on SDV channels. It's becoming more and more frequent. My cable card is cisco and tuning adapter is cisco with all the latest firmware. Either I get a completely black screen or the notice below:

    "This channel is temporarily unavailable.
    Press SELECT to try tuning to this channel again."

    Channeling up or down sometimes fixes it, but not always. I hope the fall update fixes this issue.

    I'm glad I found this thread, because I'm having the exact issues.

    Roamio Plus on Charter in Madison, WI (Motorolla TA and CC)

    The mini always tunes to the channels perfectly, as OP stated. The Roamio fails on certain channels (not always the same channels, sometimes rebooting the TA fixes it, sometimes not).

    I hope they come up with a fix soon. I've already missed recordings because of this issue.

    All I did was unhook the TA and then go thru the channels and mark which ones didn't tune.

    Please keep us up to date. If they need others with this issue, I'm willing to help out via log submission, betas or whatever.

    My advice would be to email Margret and ask about the beta programs.

    Hah. Good idea. :)

    The problem started again this morning while attempting to tune CNBCHD (1219). I think I may have a workaround for the issue. If I go into the guide and select record on the problem SDV channel, the problem appears to go away. More experimentation is needed along with a phone call to open an issue with TiVo tech support.

    FYI, I've been messing with a Ceton InfiniTV6 and realized the same "record" workaround as well SBiller, with the exact same failure to tune issues as the Roamio. I could also just hit the stop button in wmc (which tivo doesn't have) then select the channel again in the guide and it would tune. I went back and forth with Ceton tech support, they gave me a new FW to try but kept blaming the cable co, but when I talk to Oceanic TWC , they kept saying everything was provisioned and setup properly on their end (which is usually BS). Ceton finally got to the point that they asked for my account info and would call on my behalf to clear up the cable co's ignorance and get this thing finally working properly. Well lo and behold, Ceton emailed me very shortly thereafter (apparently right after they spoke to Oceanic) with a new FW to try, which immediately cleared up the tuning issues!

    I asked them what the issue was? Was it a Ceton issue or was the FW something to use as a workaround for a cable co issue? Her is their reply:

    "Hi David,
    It was determined that in a narrow set of cases, incorrect information would be sent to the CableCARD when requesting decryption of a channel. This resolves this issue.

    -Ceton Support"

    I would say this is most likely TiVo's issue as well, so anyone experiencing this should call TiVo tech support and pass it along.

    FW = Firmware, which is basically the operating system for the hardware device.

    My Mini was acting up last evening attempting to tune to CNBCHD (1219) again. The video would play on the Mini for about 3 or 4 seconds and then the picture would freeze. I could tune to another (non-SDV) channel and the Mini would stream correctly. Every time I went back to 1219 it would exhibit the same freezing behavior. I then tuned to the non-SDV standard definition version of CNBC (42). When I tuned back to 1219 it worked correctly. I did check the DVR Diagnostics screen(s) on the paired Roamio and I think I'm seeing the similar analog tuning behavior.

    PS) I have provided my TSNs for my Roamio and attached Mini to TiVo for analysis.
