    If the FCC approves then the next generation of TiVo wont support analog at all, so I doubt TiVo is putting much effort into analog recording right now. Probably just slipped through the cracks.

    I think we're missing the original post. There are no OTA analog channels in Chicago. Missing video data is from camera devices.

    Um, no. He's just explaining why reception of analog channels via the antenna might not have been tested.

    Yeah there appears to be a bug in the last software release which disabled analog input on the OTA port. I'm guessing that bug slipped through the beta because very few people have access to analog OTA and as such the chances of a beta tester actually finding that bug were slim.

    As I posted on the TiVo site, I ran my cable to the ANT input, reran Guided Setup to enable OTA and my unit found channels 2 to 13. These are the same channels as OTA and I also ran them to my Sony DHG's ANT input with the same results. When scanning for channels I normally get 2-24 and 70 and 98 on the cable inputs of the Sony. All frequencies are correct.

    I have five VCRs. Two are older and I use them to supply VBI information to the Sony. Three are digital and strip the VBI data perhaps for TBC use. I don't know. But with a firewire interface they can talk to each other. I will gladly send TiVo a VCR if it will help their testing.

    The OP is in Chicago. Perhaps having the call letters of these analog FOX and PBS channels we can determine more information? It seems channels still sending analog have -LP in their call letters. The Chicago OTA channel for Fox is 1MW UHF.

    Maybe he moved and never updated his/her location?

    The center...
    Yes, the OP is in Chicago. But he was having issues with two security camera feeds on the antenna input.

    I chimed in saying I was also having a problem with analog channels on the antenna input. I'm in rural central Arizona where we still have analog broadcast stations, including local translators for the FOX and PBS affiliates in Phoenix. (We can't get the Phoenix signals because there are mountains in the way.) More specifically, I can no longer get K36AE or K42AC.

    TiVo has asked me to do some more troubleshooting and has suggested that my Premiere's analog tuner may "have burned out." The troubleshooting will take some time and require some reconfiguration; I'm hoping to get to it this weekend.

    Your two listed stations are in the FCC database as translators of KSAZ and KAET. Your problem sounds reasonable. The FCC does show both of these as digital however. I have a translator station about 20 miles away through two very high mountains and it is digital. We both live in the middle of nowhere. I don't know about Clarkdale, but my borough has a pop. of 4k and I have mountains everywhere.

    I wasn't discounting your problem, but the chance of LP analog stations in Chicago are not very high. I can assume you sent the stations an email or called them, asking if they changed to digital? If they share a facility this would not be out of the range of possibilities and really bad timing.

    I figured Chicago would have enough "ethnic clusters" to make low power stations likely.

    I finally got around to testing if I could feed my "analog security camera" channels (via RF modulator) as a cable channel (instead of OTA UHF), and it didn't work. I suspect it's the same "bug" and/or that I use a cablecard.

    I guess I don't really understand how RF modulation works, because I tried to search the web for a DIGITAL modulator, but couldn't find one (or find one that wasn't really, really expensive)

    AFAIK there is no such thing as a consumer grade QAM or ATSC modulator. There are a few "low cost" options in the professional space that some of the guys on AVSForum use for whole house distribution, but they're like $3-5K so probably not what you're looking for.

    You might be better off finding a cheap S2DT TiVo with lifetime and using that instead for the security cameras.

    Thanks Dan... yeah, $3-5K is just a wee bit too costly :)

    FWIW, I already do use a S1Tivo (with lifetime) for one of the security cameras, but then I take the channel 4 output from that into my Premier (which has a slingbox), yada yada...

    I bought a security camera DVR on woot.com that lets you record from 8 cameras at the same time (and included the 8 cameras) for like $150.

    The latter. You can't scan for cable channels if you have a CableCARD installed.

    FWIW, just for grins, I tried this again...
    still does not work under the Fall 2013 update.
    sucks that Tivo would just take away previous functionality
    (and one of the reasons I bought this particular model)

    The TiVo should tune NTSC signals on the cable tuner, 'cause that's what analog cable is, the same thing as over the air used to be (except for the carrier frequencies of some of the channels).

    Of course if you're trying to use it for TV watching as well as camera recording that probably doesn't help you.

    Not all of them are lined up the same way. For the OP, it should be set up as cable, as that's what would be RF modulated. Who is watching analog anymore anyways? It must look horrible. If I had some back-asswards station that wasn't broadcasting HD by the early- to mid-2000's, I'd sure as heck have gotten DirecTV a long, long time ago!

    The problem is, if you have a CableCard the channel map from the card overrides analog channel scanning. For example, my system has digital simulcast of all of the analog channels, so if I hit channel 2 on my TiVos with a CableCard, I get the digital equivalent of channel 2, not the actual analog signal.
