    I am a Spectrum subscriber in Round Rock, TX with TiVo Roamio Pros running 20.7.4b.RC3-840-6-840 with a tuning adapter and multi-stream CableCARD.

    Lately some channels are not staying tuned after initially successfully tuning. Specifically, I can change to the channel and the picture and sound will show correctly for about 3 seconds, but then the following message is shown

    This channel is temporarily unavailable.
    Press SELECT to try tuning to this channel again.
    Contact your cable provider for more information.​

    If I press select, the tuner will tune correctly and show the video/audio for another 3 seconds before showing the message again.

    If I power cycle the tuning adapter, things will work correctly for a short period of time (I think measured in minutes and not hours, but I do not know for sure exactly).

    This only happens on one of my 2 TiVos.

    The channels that fail are "lesser" channels, so I thought perhaps it was an SDV issue, but I know that some of the failing channels are ones that would show up without the tuning adapter connected (e.g. HBO on 511).

    I have captured the diagnostics for a working channel (7) and a fialing channel (125) (any typos are mine):

    How do I go about determining if this is a TiVo issue or a CableCARD or tuning adapter issue?

    My guess is a tuning adapter issue or an issue with Spectrum. Unlikely to be a problem with the TiVo or the cable card.
