    This makes the somewhat dangerous assumption that DIRECTV includes the sub-channel in question in their guide database.

    If I had known about the scanning ability (or lack of) on the AM21, I wouldn`t have blown $50. The whole idea was to keep my parents from having to (and usually failing) go back and forth from DTV to OTA for the subchannels. They wish they had stayed with Dish, where this isn`t an issue.
    (It was my idea to switch them to Direct)

    They are currently not adding anymore OTA locals to their database. We were told some time ago that the database had grown too large and no more could be added.

    Then why waste $50 dollars on an AM21?

    Because it allows you to record them like any other sat channel, which you cant do with your tv.

    As does mine. It's better than my TV's tuner and MUCH better than the old converter box I have floating around. AM21 = awesome. Except for the lack of some subchannels.

    Can anyone verify that the HR34 actually scans OTA with the AM21?

    Yes, it does. However there is no guide data for channels it finds that are not in DirecTV's database.

    But just to make sure.....there IS guide data for those subchannels that are in the database? And it will pick up and record (without a guide) channels that are not in the DirecTV database at all? We have a couple of those here in Austin.

    If the channel is in DirecTV's database of OTA channels you will have whatever guide data the channel provides. You will still be able to record if there is no guide data but you will have to setup a manual recording providing date, start time and end time.

    Can`t record a OTA channel that doesn`t exist in DTV`s database.
    And there are plenty of them in NE Ohio.

    You're missing my point. My point is you can't record any of them at all with your Directv equipment if you dont have the AM21 to begin. I understand you're bitter about not being able to get some 2-bit crap channels in NE Ohio that you can pull in with your tv. :lol:

    My parents live in NE Ohio, believe me I know what crap they broadcast there.:)

    Any message that offers this information should include a note that this applies uniquely to the HR34. This is too hot a topic to chance creating any confusion.

    I do (actually I bought it for my parents) have the AM21. The problem is they could get everything ota with Dish, before I talked them to switching to Direct TV. Now, they can`t pick up some of the old shows on some the subchannels because Direct`s AM21 doesn`t recognize their existence.
    (BTW, I won`t disagree on some of the content, I never realized just how bad some of those old shows really are). But the old folks like them.

    This is interesting. I wonder if a firmware update to the non HR34s would allow the AM21 to work the same with them, be able to record manually without program guide data. That at least would be a step in the right direction.

    The AM21 depends on DirecTV for guide data. It can't see any OTA channels that DirecTV doesn't have in the database. So why would you want it to manually record?

    If I'm wrong, someone PLEASE correct!

    The AM21N (new model), when combined with the HR-34 will scan for channels. It still uses the database, but can make use of the channels it finds in a scan. It is the only HR box (current), that does scan for channels. (no program info, however)

    That always seemed to be such a bogus answer. What could be so difficult and expensive about expanding a database?

    Because it expands the cycle for downloading the guide for everyone. The guide data is transmitted via satellite and the receiver decides what data to use. That means if you double the number of stations in the guide data, you double the time it will take to get from the first station to the last, and that means potentially doubling the time it takes for a receiver to load guide data on a reboot. If OTA stations double the number of channels in a particular DMA, you also double the size of the guide data in the receiver, and potentially slow the receiver even further.
    there are ways of managing the guide data that would not have this same problem, but I think when the DirecTV system was designed no-one anticipated the potential problem with OTA channels.

    Texasbrit - I think you're right on target there.

    Twiseguy - I understand your situation (I'm very much in the same boat). Perhaps you could explain the situation to DirecTV and arrange with them to upgrade your parents to the HR34/AM21N combination that would at least detect the subchannels of interest to your parents through its scanning capability and therefore be able to tune them (although the guide data for those stations would apparently still not show up on screen). Alternatively, perhaps you could place a two-way splitter on your parents' antenna line, to feed it simultaneously to your parents' AM21 and to their tv tuner. Then, at least they could switch inputs with the tv remote from DirecTV to antenna and use the tv's tuner to tune the subchannels of interest. It's a shame this is so poorly designed.
