There are a couple of issues here.
For channel 836 (Fox Sports Southwest HDTV (Dallas DMA) 24/7), I do see two airings marked as “New” which I do not believe they are. This has been referred to our provider
For channel 934 - the issue is due to the airings being marked as “Taped broadcasts”. We currently mark these as New and this needs a refinement at our end to check other data items. This has been raised for our team to look into
With regards to
I’m recording every airing, even when I have the episode with the same air date already.
This should not be the case as the episode should be found in the library and not recorded. I would like to see a Plex Media Server log with debug logging enabled if it is not doing that and you are using the current version of Plex Media Server
I do see you have one old server on 1.16.5.1552-8e8d0c785 - is it being used for DVR ?
Of the above list of airings, these airings are the same episode and should only result in one getting recorded

and similarly these

There should only be one recording made for each of these
With the “Sport” tag on these and using current version of Plex Media Server, there should be no tvdb matching at end of recording and the episode will remain labelled as per the EPG allowing the check for already being in the library to work
