Does HD DVR accept digital OTA?

    Nope, it always tuned ATSC, not NTSC. If you're having problems since the switchover, it may be due to some of your digital channels shifting their "true" channel assignments (may need to shift your antenna) and/or your HR20 having mapping issues (may want to reset your DVR and completely re-do your OTA channel setup).

    All three units are fed from the same multi-switch. It can handle, I think, eight lines, and only six are being used, two for each DVR.

    We may have a terminology issue here. I have an antenna feed that goes into the back of my HR20. When it was feeding an analog signal I had no problem viewing it. I have no idea of exactly what was happening between the antenna feed and the TV. Like a Mac, it just worked.

    You could not have been viewing an analog signal on the HR20-700, period. This box is digital only. I've had the HR20-700 since before it had OTA capabilities and it never had the ability to receive analog channels.

    Connect a good VHF/UHF antenna to the HR20-700 and re-run the OTA setup from scratch. At that point, whatever you can get you will get.

    You may be having a problem with the channel info that is being presented to the HR20-700. That info comes from Tribune and it has errors. This will give you a 771 error on a perfectly valid channel because the database is telling the HR20-700 to tune to the wrong frequency. Until that is corrected, you will not be able to receive it.

    As a test, connect the same antenna to your HDTV (with tuner) and scan. See what channels you get. You should be able to get those same channels with the HR20-700 after you delete all channels in the antenna/OTA setup of the HR20.

    If you are still missing channels (compared to your HDTV), then the problem is most likely an error in the database. You will have to contact Tribune to get them to fix the problem (or call your local TV station's Engineer In Charge and he may do it for you (mine did).

    You may have been fooled by the channel numbers. There is no certain correspondence between a channel number and its frequency in the digital world. They can make your TV/STB display any channel number they want (subject to FCC rules, of course). Go to tvfool.com and enter your information and you will see what frequencies your channel numbers are really on. It will also show you what channels you should be able to see and their relative strength, as well as what kind of antenna it will require.

    And an aside - NONE of the HD DVR's D* has ever made, could pick up analog signals

    You couldn't view analog OTA channels on HR20. The receiver is only capable of receiving digital channels. As someone suggested, some of the station might have move to a different channel. If directv updated their database, and most likely by now they have, re-doing setup will fix your problem as long as you are able to receive the channel.

    The H20/HR20 strictly have a tuner capable of tuning in digital OTA only. to many that means HD, but there are still SD digital stations out there. You'll notice that it only pulls in channels with -1, -2 etc...via the antenna it has never been able to receive analog locals. Never channel 47 for instance, just 47-1, or 47-2...on the back of your HR there are 3 coaxial inputs, ANTENNA IN, SAT1 IN, SAT2 IN...the OTA channels show up as the black lines in your guide, as opposed the sat channels which are blue guide lines

    Those with RF input/outputs can however, pass analog RF through to a TV, when placed into standby, or turned off.

    Nice catch...that could also create the false impression that he was receiving analog channels on an H* box..but he was referring (initially) to the HR20-700 and I don't think it can do that. (or if it does, I never bothered to use it:))

    In the days of analog TV, if I connected an antenna to the antenna input of my HR20-700 and got a picture on my TV, what on earth was happening? Do I have some sort of weird, experimental HR20-700?

    Maybe that is the explanation. Have commercial channels always broadcast digital as well? I never knew that. I thought it was something that only happened in the last few years. I used to watch OTA before local channels became available and it never occurred to me they were already digital.

    At this point I no longer remember if they showed up as, for example, 2 or 2-1.

    At any rate, the problem only cropped up after analog was dropped so I assumed it had something to do with that. It may actually have to do with channels being re-configured to new frequencies.

    Thanks, everybody, for the advice. I'll re-initialize my OTA channels and see if that solves the problem.

    Have you checked with the stations themselves? It could be the station(s) are doing work on their atennas, you also could be in an area that is changing their antenna height/locations. Many areas of the country will not be fully operational with digital TV until the middle/end of Oct. As was mentioned re-run your set up again. You also could have other issues causing the problem, check your cables to see if possibly an animal has chewed on the coax (happens a lot), the weather could be causing the signal to not be as strong etc. There are many issues that can come into play when your dealing with OTA. Do you have a TV that has a digital tuner, if you do run your antenna directly to it and see what channels it finds on a "scan." If it finds a lot more channels then you know it's an issue with your D* box (or Tribune), if you don't get anymore channels then it is either the OTA signal itself or your antenna isn't working. Many antennas were sold has "HD antennas" that were really only good for UHF and as channels have gone back to VHF people have found out their antennas won't do the trick.

    You GOT it - in many areas, local OTA digitals that were on one freq, HAD to move to another one on analog shut-off day. In my area, our local CBS/MNT, which previously was on digital 53, moved (again) to digital 13. In some cases, many stations were on temporary digital channels, & then moved the digital signal BACK to their old analog channel. In all these cases, rescanning ALL OTA tuner devices is/was a must.

    This is also true if your digital locals add or change subchannels - just last week, our local CW affiliate added THIS TV to 23.2. Even though it was showing up in my 2 HR20 guides, it would NOT tune - I had to delete & rerun OTA setup to get it to come in. ;)

    That's a trick statement. DIRECTV has never made an HD DVR.

    None of the current DIRECTV "HD" DVRs have RF outputs nor passthrough capability and most of them don't have OTA inputs anyway.
