Recording fails when season and episode information is missing from the guide data

Postby MatthewLundberg » Tue Jun 12, 2018 6:40 pm

RECORD Version 20171221

Quite often, the season and episode data are missing from the guide data for programs. When this data is missing, the DVR often (but not always) refuses to record a second episode when two are played back-to-back, thinking that it's just recorded it.

Prior to the first recorded episode at 0100, the target directory was empty. The DVR should be smart enough to not assume that two back-to-back episodes are the same. It's not the same. This causes recordings to be missed.

Are there any settings about duplicate shows, for example, to always just record them anyway and let me deal with the fallout?

Here's an example from the DVR log:


20180613-01:16:38 Recording: record Doctor Who [20180613-0100] on 13.2 (28 9)
20180613-01:16:38 Recording: record Doctor Who [20180613-0100] on 16.1 (28 1)
20180613-01:16:38 Recording: record Doctor Who [20180613-0130] on 13.2 (28 9)
20180613-01:16:38 Recording: record Doctor Who [20180613-0130] on 16.1 (28 1)

You should update the Record engine (20180418). With that said, it appears some metadata is missing. Unless those are Dr Who movies, there should be season, episode and original air date info in the file name.

They're not movies. The data you reference is missing from the guide data. This happens quite often. In the past, it used to always record episodes where the data was missing, now it seems to always think that they're duplicates, if there's another recording that's missing the data.

I'll try updating the Record engine and see if I notice a difference, but I think the prior update brought on the current behavior.

I think this is the case. When the guide uses initial series air date for all episodes, the system appears to think they are duplicates and does not respond. I think this is why "Democracy Now" does not automatically record for me even though I have it set to record all episodes. I can select it to record individual episodes and it records fine.

In this case, there is no data for the initial air date. There is only a generic description for the episode itself ("Doctor Who" is a classic science-fiction series with a cult following...).

The episodes also show that they have a recording rule when I look in either the guide data from SD using the web API, or in the Android interface. To set them to record as individual episodes, it seems that I would need to disable the series rule, then set the individual episodes to record, then remember to re-set the series rule (and frankly, I'm not convinced that it would work).

Dr Who isn't airing at all in my location. New episodes in October I think.

For some reason, the listings for RetroTV through 6/24 don't have episode information, but they do for 6/25. I've opened a case with Gracenote to see if they can add the missing episode information.

Any chance of defaulting to recording an episode if the series/episode is unknown?

These are reruns on Retro TV. They're from the sixties.

Never heard of RetroTV, but all those episodes from 60s should still have Season/Episode or Original Airdate. Hopefully Gracenotes can fix it for you quickly.

I might be able to make the case for a new option to record every airing no matter what (i.e. ignore duplicate detection), but I'm not sure about changing the behavior of the existing ones. There are a lot of potential unintended consequences with legit repeats that are missing data because the channel rearranged their schedule at the last minute and didn't get proper episode data to Gracenote.

Retro TV was one of the very first subchannel networks back when they started getting popular. At this point they're just barely hanging on mostly on low-power stations as many of the bigger players in the industry launched their own channels and got better carriage deals and picked up the rights to most of the popular shows.

Gracenote has data for all the seasons so I'm not sure why they don't have the episode numbers associated.

Another issue with RetroTV is that I receive it on two channels, logical channels 16.1 and 13.2, which might throw a wrench into always recording every episode, no matter what.

I believe that I've mentioned it before, but it would be ideal if I could record both of them and have the channel number encoded in the filename, because they're flaky channels and often enough one of them is off the air, but very rarely are both out. And I like a lot of the shows that they play (including the old Dr Who series).

I don't think anyone expected anything to change with the latest version, but it did not. It again did not record the second episode today.

Gracenote did acknowledge the ticket and is investigating. Even if they are able to correct the issue it will likely take until the next day for it to percolate through their system and into ours.

Gracenote found an issue that was causing the episode information to be missing, and they have resolved it. The data should be in place for tomorrow's airings.
