Tvheadend

Hi all running unstable presently on build 4.3-952.
From around the 13th of January, the recording files have had the title and subtitle restricted to 7 characters.

Eg Peppa Pig - Hospital
Was saved as tvshows/Peppa P/Peppa P - S03E32 - Hospita.mvk

Was expecting tvshows/Peppa Pig/Peppa Pig - S03E32 - Hospital.mvk

File format string is set as $q$n.$x

Was working good before this.

Think it may have been an update on the 12 that has caused the issue.

Have tried rolling back however the guide did not work on kodi

Using DVB-T in Scotland.
Using Over The Air EPG only.
Any Ideas?

Thanks
Derek
