Where is the tvshow.nfo file getting data from?

[Deihmos 170]

I turned off all metadata lookups for recordings because they’re usually inaccurate. I’ve noticed that the tvshow.nfo files still contain random data for shows that don’t match, so I’m wondering where this information is coming from with metadata disabled. For example, Zap2it no longer exists, and Cuomo Prime Time was canceled years ago. The guide data appears to be correct, and the posters are correct.  Basically, the files are filled with unrelated data that doesn’t match what was actually recorded. Shouldn't this data come from the guide?

Hi, it could have been guide data, although given the presence of IMDb ids it looks like that example was guide data that got merged with internet metadata.

i have all metadata lookup for recordings off. I still believe it would be great if emby got the backdrop from the guide instead of using the poster as the backdrop.
