Roamio OTA not recording

Ok. That's pretty wierd. Couple of things:

1. Are the channels you wish to record from listed as channels you receive in your channels listing?
2. Have you tried manually forcing a recording and seeing if records and stays?
3. Maybe try rescanning channels?

After that I'd take this up with tivo support. If this was an actually brand new tivo, you should be able to get warranty support for it.

 

Does the red recording LED come on when it should? Is there an entry in My Shows while the show is (supposedly) recording? When you watch live, do you see a progress bar, and can you back up and replay normally within the 30-minute buffer? If certain timing information is missing from the broadcast transport stream, "trick play" functions won't work properly, and after the programs ends the TiVo will discard the My Shows entry because it thinks that nothing actually recorded. But that problem would be with your local broadcast station, and if several different channels are failing to record, it seems unlikely that they would all have such problems.

 

What antenna did you mount?

Anecdote:
Connected a new Roamio Basic to a 4 bay bow tie antenna, which "should" only provide UHF frequencies (expected.)
And, much to my surprise I got all locals here in Torrance... during the day.
At night the Roamio would only tune in UHF stations, in my case, cbs-2, nbc-4 and ktla-5.

Could just be the antenna.

 

He stated that he's able to watch the program that he wishes to record through the tivo, while it's supposed to be recording. But that it doesn't actually get recorded.

Is there a scenario in which he can watch the program live but not record it that could be caused by the antenna? My instinct is that if the antenna is correctly delivering the program to be watched live, then the tivo should be able to record it. Is this instinct wrong?

 

Thats what I would think, the only time I don't get any recording at all is if there is no channel lock. Even if there is a lock for a few minutes with a non-watchable picture I get a recording. Sounds like something he will need to get worked out with Tivo Support.

 

Perhaps he is watching the program on one tuner but a different tuner (bad?) is failing to record. Hitting Info then down during the recording would answer my speculation. I've never tried to have all tuners on the same channel then having a recording start for that channel. Maybe I will.

Update: that would do it. Not saying it did, just that it could.

 

I don't know, I asked a question.
Supplied a personal experience.
Stranger things have happened...

 

How do you mean you "navigated to the channel live"? I don't think you can tune the exact same channel on a second tuner. If it happens again, start your (second) recording from live TV, then look at TiVo Box Diagnostics to see exactly what each tuner is receiving. You might have two channels in your channel list that have the same number but which are not identical (due to different RF frequencies, for example, or even just different program IDs).

OTOH, if you could see the first recording as it recorded, even though the time was shown as 0 minutes, that might indicate that timing information in the transport stream is incorrect or missing, as I mentioned earlier.

 

Having the same problem repeatedly with ABC on certain shows only and in some weeks only of the season pass via antenna with the roamio. During recording, the episode is in my shows list, but if you click on play, you can't see it. After recording ends, it disappears from the my shows list. History says "not recorded, no signal". However, the show can be viewed as live tv, so no signal makes no sense. Signal strength was fine. Rescanned channels and reset and problem continues with the shows. No recording conflict. This has happened whether no other show was recording or only one other show. Different shows on same channel same evening recorded fine on their season passes.

 

What you're seeing might be consistent with some timing data (Program Clock Reference?) being missing or stuck (not incrementing) in the transport stream. TiVo seems to rely on proper timing information for some functions like trick play. I've seen this with OTA broadcasts from a local translator (re-transmitter) for one of our PBS stations when a piece of equipment which inserts new PSIP data goes wonky. When the program ends, the TiVo sees that the time apparently didn't advance, concludes that nothing was recorded, and deletes the recording even though everything but the timing information is actually there.

 

Did you ever figure out the problem here? I have a Roamio OTA that does this with ABC as well. I bought it 2-3 years ago and gave up on it and went back to using my older Premiere Tivo. The Premiere worked fine but the fan starting going out on it and makes a terrible noise. I switched back to the Roamio OTA hoping whatever issue it had would be resolved by now, but it still misses shows on ABC. Somedays it records but most days it doesn't. I think it records, but at the end of the show, it goes away and shows "no signal" in the history. I saw your post was from 2016 and wondered if you figured it out. I will set it up for manual recording to see if that helps.

 

I have a roamio plus which suddenly started doing the same thing on NBC this week. You can watch the show ok live, but after it is over the recording disappears and history shows "not authorized". I will also just put it on manual recording....

 

My xl4 (timewarner cable) and ota roamio failed to record station 19 last night.

 

Try rescanning antenna channels to see if that helps.
