Recorded filename format has changed. Not sure what version this changed at.
Just wondering is it a bug or was it changed on purpose for some reason?
Filenames used to contain the Original Air Date if it's available from gracenote.
example: Forged in Fire S06E31 2019-09-25 Genghis Khans Sword 2019-09-25-2100.mpg
Lately it's not part of the filename even though the schedule and recording json data contains it.
example: Forged in Fire S06E32 Sword of Perseus 2019-10-09-2100.mpg
Recording (files) json data shows
"OriginalDate": "2019-10-09"
"releaseYear": 2019
"releaseDate": "2019-10-09"
"origAirDate": "2019-10-09"
MCEBUDDY hack json metadata file shows
OriginalBroadcastDateTime "2019-10-09T00:00:00Z"
I use the OAD as part of the filename, so since it's now missing I have to discover it and add it to the filename when processing it out of the Channels DVR directory.
