    Espo - I see the same options under the CC menu (these are the screens for SA CableCARDs). In the Diag screen, my RF IP Addr also says "None yet..." I don't know if that is normal or not.

    My HostID screen shows just "CableCARD:" and "HOST ID:." I think the other items appear in the pictures you mentioned because they were using Motorola CableCARDs, and the SA cards like we have don't have those.

    I think the main screen to check is "CP Screen." What's do the various status items say (for instance"Auth Status")?

    I'm in Columbia, too, and am highly likely to switch to Verizon myself, should they ever get to my neighborhood (they laid down cable over a year ago and haven't begun offering service here yet).

    If Comcast can't fix this CableCARD problem before Verizon begins offering service, I don't see what they could possibly do to keep me from switching.

    When they are working they say "Received" & when not they say "Failed'.
    It seems strange there's no RF IP Address being used. I'll compare it to FIOS cards on Tues. I believe they use Motorola as opposed to our SA cards. Verizon did say they were going to be getting multi-stream cards very soon. Sounds like we'll be able to use those with a future update from Tivo.

    Mine also says "received" and changes to "failed" when the problem occurs.

    By the way, there's actually a more general separate thread for this, but I'm wondering if it's related to problem discussed here: Those of you near me with the same problem with G4, if you take G4 out of the channel list, does it appear back in the channel list (become checked again) by itself whenever you reboot?

    Ditto. Same with me.

    Hey, we should all have a Tivo Meetup. We're all within 10 minutes of each other.

    The FIOS went thru yesterday without a problem (except for some hesitation from the tech for his inexperience with a Tivo install). The Motorola CC menus seem to be much more useful in pairing up the cards compared to the SA cards. They went on after a few minutes once the numbers were entered correctly. I didn't experience any of the problems I've viewed with Comcast - missing channels, break-up when moving thru the Guide, & no audio glitches (so far!). Verizon's channel grouping is also much more logical - CNN with other news, MTV with other music, etc.. None of the Comcast mess (channel 5=Fox45, 75=Fox5!?!). Also, many more channels including DC HD locals, HDNet, HDNet Movies, NGHD, NFLHD, WealthHD?, & FUSE. You do lose INHD (no biggie) & CSNHD (V claims to be adding this).
    Overall, I was very pleased with the install, with the tech being being very helpful & professional. Instead of convincing me I was wasting my time by not using their equipment, he was very impressed with the S3. I've decided to cancel Comcast & wait for FIOS to be turned on on my street - hopefully only a few months!.

    Espo,

    I'd be really interested to hear how the FIOS service works for you once you get it. If it solves the problem discussed here as well as the audio/video drop-outs, I'll definitely switch. It's available in my area, but I didn't switch because it didn't seem like it would be that much cheaper for what you get and it's just a pain to switch. But this would be reason enough to make it worth it.

    Thanks.

    It's taken me some time, but I've gotten back to debugging this.

    I got a second S3 recently, and today had cable cards installed. As expected, it does not receive the problem channel (68), just like my other one and everyone else's in the area.

    Since Comcast has refused to try a CableCARD in another device to see what happens, I told them I just wanted one for my TV and paid to have them come install it. Interestingly, the TV can receive channel 68 just fine. So unfortunately, this seems like a TiVo problem.

    I called TiVo and gave them this information. Their reply was to wait and see if the 8.1 update fixes the problem. In the best case it will, but apparently if it doesn't we'll have to wait until it's released for them to even begin investigating this. :(

    TiVoJerry recently posted about the missing Audio issue because CableCos aren't adhering to the requirements/standards to include AC3 audio streams with every channel, and throwing in MPEG audio sometimes.

    Fault is known.

    TiVo is still being nice enough to work around this, and he did say 8.1 would fix it.

    I'm being lazy but will claim I can no longer find the thread :)

    Only the problem we're talking about isn't the missing audio problem. I can't receive the channel at all - no audio OR video. (Actually, is there a way I can change the thread title? It seems like it's a bit misleading, as a couple people have thought it was about the missing audio problem.)

    So I think the fault is still yet to be ultimately determined...

    However, I just read something in this thread that may indicate it is indeed a Comcast problem. Apparently if we look on the diagnostics screen, the PCR PID and Video PID that are listed should be the same - for me on this channel, they are not. So I may have the same problem that hookbill describes on that thread (which would be good since it seems like there's a known solution to it).

    Gotcha! Yeah, I only skimmed your post and thought it was the same problem.
    Good luck

    I hope this is it, too. I am having you same problem, only on TW and the Fuel channel. If I tune to it for more than a few seconds (of black screen), I get rebooting CC's. I have mismatched PIDs on this and some other channels (which do not work). Interestingly, I have mismatched PCR PID and Audio PID on the Fox Soccer Channel (though Video PID and PCR match), and I get video, but no audio. So it seems like we're heading in the right direction.

    Go Howard County people! I'm in Columbia too and I just ordered my S3 last night. Because of all the CableCARD issues, I'm not in a rush to call Comcast and dump D* as I would much prefer reliable service. For right now I'm going to try out the free QAM stuff (in addition to OTA), of which I can see through my TV now.

    Speaking of which, is there a guide to channel mapping for Howard? I can't for the life of me find FOX45. I had lost CBS, but I found it again with a rescan.

    I'll search around again for how to deal with Comcast if and when I try the CableCARDs out, but any hints you can PM me would be appreciated.

    I think it's okay that it's different (my audio PID is different from video and PCR on every channel), but I'm sure it could still be the wrong audio PID. Do you by any chance have a set-top box that can successfully receive that channel? In my case, I've now been able to use the diagnostic screens on a set-top box to determine what the PCR, video, and audio PIDs should actually be (looks like the TiVo is in fact getting the wrong video PID).

    Of course, there are other possible explanations for the channel that is just missing audio, like what ashu mentioned. Admittedly it would be kind of unfortunate if the cause of the problems is different on some channels than on others!! :eek:

    I think you're right - I'm especially interested to hear that this is causing problems with the CableCARDs for you, too. You mentioned "rebooting CCs" - do you mean that they do the same thing as we've seen, where they stop working until you reboot the TiVo?

    Also, one other thing I was wondering - what brand of CableCARDs you have? I'm wondering if the severe bad reaction to this situation (requiring a reboot) is unique to Scientific Atlanta cards.

    Too bad we didn't realize what each other was talking about originally. We could have had only one thread on this......Oh well.

    I mentioned on the thread I started but i will mention it here as well. My channels that had audio problems have been fixed. They asked me about that as well and I guess in the process of taking care of the problem channels they fixed the audio onces as well. I have no idea how that was taken care of but on Monday I will probably speak with Jo Anne at TW and I will find out what was behind that. That is unless Hallmark channel happens to come on between now and the time I call her. :)

    Good idea. I do. (Had to keep it until the TiVo got sorted, didn't I?) I will try to find the appropriate numbers. Of course, I'm limited in that if I leave the TiVo on one of the "bad" channels for more than a couple of seconds the CCs reboot...
    Not exactly. The card itself "reboots" if that's the right term. It goes back through the authentication sequence. I.e., when I pop in and out of the CP Status page (it doesn't refresh itself) I see:

    Auth Status:Waiting for CP Auth
    Auth Status:CP Auth Received
    PowerKey status:Not Ready - Waiting for Time
    PowerKey status:Not Ready - Waiting for EUT
    PowerKey status:Ready
    MKS Period switches from 60 seconds to 100 seconds
    Test Channels shows "No Channels Available" for another minute or two
    Test Channels starts displaying all channels except the bad ones
    I do have the SA cards.

    Just wanted to follow up on this post. I switched to Verizon FIOS for internet & tv a little over 3 weeks ago, and haven't had this problem since. I can receive all channels, and none have blanked out on me. It's also cheaper, so if it's available to you, you might want to check it out.

    This is good information. I have Cablevision in NJ, but FIOS just became available to me and I am interested in getting rid of my problems caused by the S3/Cablevision/SA interaction. Good to know that FIOS has fixed your problems.

    Brainiac: Same problem here in Elkridge (Howard Co. - SciAtl CCs). This sure sounds like Hookbill's problem. I went ahead and removed G4 from my channel list for the time being. Also, do you get National Geographic HD? All the Guide info is there which makes me think I should be able to tune it, but I can't. I think there was another channel near that one that is the same. Discovery HD is fine, though.

    I've got a decent Comcast tech coming by on Wednesday (for a totally different reason) and if we had enough info, I'd like to pass this on to him. Any new info?
