Thank you for your assistance. I am located in Hot Springs, AR and my cable company is Resort TV Cable.
Correct...no tuning adapter. One other bit of information - We've had TiVo's since 2003, so this problem suddenly cropping up was strange, but sometime within the last year my cable company has made the switch to some type of new service...all digital? Something like that? I can't be positive but I'm thinking my problems may not have started until after their conversion. But again, I'm not 100% sure.

Make sure your wiring layout makes sense... Do you have lots of splitters, possibly leading to low signal levels at certain points?
Do you have any really ancient splitters rated to a really low frequency range?
Has the cable co come out to check your signal levels?
What happens differently on Sundays? More people home? More appliances being used? Anything that could generate a lot of rfi/electrical interference and cause things to get glitchy? Does the church next door throw wild parties and are making your electrical service brown out?
House is 15 years old and everything was wired during construction, so wiring *should* be good. The last time a technician was out he did replace what appeared to be a bad end on the coax coming into the box on the house. We sit about 1/2 mile from the road and although we are a great distance the tech did say we had an excellent signal. All wiring is underground from road to house. He didn't think it was a signal issue after he took the readings.
There really is nothing that happens on weekends that doesn't happen each weeknight after school and work is over and no wild church parties that I know of.

In DVR Diagnostics what is OOB SNR ? Normally this is around 26 dB.
And how many seconds for "Time Since OOB Tune Start"? This should be the time since you last rebooted the TiVo. If it's much less it probably means the OOB signal is dropping out and then retuning. OOB means "out of band" and this is how the cable system communicates with your CableCARD. I'm theorizing that OOB dropouts could cause your CC's to lose their authorizations.
It's disappointing that very few cable techs understand CableCARD (or Tuning Adapter) signaling or have instruments to diagnose them.
Okay, here we may see something interesting.
OOB SNR = 2 dB.
Just for fun, I looked it up another TiVo we have in the bedroom and it was fluctuating between 23 dB and 25 dB on that machine. Big difference between the two machines.
Time since last OOB Tune Start = 185,580 seconds = approx. 52 hours? Right? Last reboot I did was on Saturday afternoon-ish. I checked the above tune start reading at 10:45 am on Tuesday. So that isn't too far off, right?
The tech that was out last week admitted to me that I am one of only about 30 customers that use CableCards, so he was pretty much telling me he didn't know that much about them.
If your theory is correct about the OOB dropouts, what might be causing it and what (if anything) can fix it?
Thank you again for your help!
