Re: CableCard "diagnostics" displayed on TiVo

Can you post pictures of the screens you are looking at?

Re: CableCard "diagnostics" displayed on TiVo

I will try. Do you have a TiVo with a Comcast card?

4XL
Excuse the cell snapshots - camera is on loan. Do I need to explain where they're located?

One of my concerns is that on the 4XL the SNR is a match to the receive of the cable card but on the 2XL you'll notice that it's 2dB but if I go to the tuners they report 32 - 34 dB.

Also one card has OOB Spectral Inversion ON (the one with the lower KHz/2XL) and the other has it OFF.

What is Spectral Inversion?

Are you getting the problem on both Tivo's or just one?

When I have issues it on both machines at the same times. Are you familiar with the screens that I posted? I have what I believe relatively high Corrected & Uncorrected errors on both machines.

Which of the two screen shots should be correct? One for both machines or are the screens correct on each as they're displayed?

Would a fresh hit maybe do anything for my concerns? What happens if I swap cards machine to machine?

Ah, I see that you are under the DVR Diagnostics screen. Keep in mind that there has been some talk about the latest TiVo software being a little screwy in the diagnostic update sdreens with not updating correctly. On my Premiere 4, I'm seeing an OOB Frequency of 7400 KHz, an OOB Data Rate of 2048 Kbps, OOB Spectral Inversion is off, and OOB SNR is between 34 and 35 dB. Same with my other card in my 2 tuner Premiere. Both are Cisco branded PKM 801 models. »www.cisco.com/en/US/prod ··· 26_a.pdf

If you swap the cards with each other, they'll still work but copy protected channels such as premiums won't work until you call in and pair them to the new Host ID of the TiVo's.

Question is, are you having any issues with either box? If not then I wouldn't worry about it. I've seen both and generally regarding OOB stuff it depends on how the CableCard is provisioned on Comcast's network before they make them available to customers both either way should in theory work fine.

Like I mentioned in my post, an unusual amount of errors both corrected and uncorrected with audio drop-outs and tiiling or pixelation - whatever one wants to call it. Comcast has pretty much verified my equipment (cables etc) to be fine. They've done they say distribution work in the area BUT I still have the unusual error counts. This was the only thing that I saw different in any of the CableCard screens. I hate to beat on Comcast and I thought the more I understood about it the more intelligent conversation I could have with them when I call them.

I applaud you for wanting to be more educated and informed about things like this. The only issue I see is the fact that the techs on the phone are clueless about things this complex. This is engineer and field technician type stuff. After Comcast did their distribution work in your area, are you still experiencing the tiling and pixilation and audio dropouts? I would have a tech come out and visit and have him run diagnostics on the lines in person, if you still are.
