    I originally called Comcast tech support. They gave me a # that is suppose to be for cablecard support only. I called that, used Comcast chat, had a technician to my house. None of them have been able to solve the problem. If you have more information or a different #, I will try that also. Thanks for the advice.

    This is happening to me also on the Sarasota head-end of Comcast. Got lost recordings due to 'No signal' on a channel I was watching before I went to bed!
    I used to have these problems with an S3 and two cards, haven't had this with the Premiere XL and single M-Card until just recently.

    The Cable card pairing number is

    I guess it was easier to refer you to another thread to find the number.

    I still have not been able to get this issue resolved. I am also in the Sarasota, FL area (zip 34232). Tivo says it is a Comcast issue (SNR signal is too high at 37 dB). Comcast says it is a Tivo software issue and refuse to change the signals. I have talked to Tivo tech 3 times, had a 3-way conference call between me, Tivo, and Comcast, talked to 2 Comcast supervisors, and had 3 Comcast tech visits. The last Comcast tech said this was a nationwide problem that began with Tivo's software upgrade dated approx. May 24. Comcast said they sent the problem to their engineering dept. on July 3rd to try and find a fix. At this point, I don't know who to believe or if this will ever be resolved. They are suppose to contact their Tivo customers, if they find a solution. I will wait a little while to see if there is a fix. If not, my options seem to be discontinue Tivo or switch to Verizon. However, Comcast claims Verizon has the same issue. I don't know anyone in my area with Tivo, so I cannot verify this. If anyone has any feedback about Verizon and Tivo, I would appreciate it. Thanks.

    As near as I can tell, my new problems started with the 20.3 update. Before that, I would get occasional "channel not authorized" or "problem with signal" messages. The oft reported rumor was that this had been tracked down to a problem with the firmware in old scientific atlanta cable cards (which is what I have).

    After the 20.3 update, the TiVo software seems to have been deliberately designed to beat the poor cable card to death, triggering this (possible) firmware bug infinitely more frequently.

    Comcast says I can't get a firmware upgrade till they roll out their system wide infrastructure improvements in Florida (which might happen sometime around October/November, maybe, possibly, perhaps, if they aren't postponed again and the latest rumor is correct).

    It is clear from the difference following the 20.3 update that the TiVo software could be much more gentle with the cable card. I can only hope this rumored patch will get it back to being no worse than it was before 20.3 and will happen much sooner than October/November.

    If they want volunteers to go back to the old TiVo software, I'd be the first in line to sign up for that :).
