So - I’ve managed to get back to a clean 8.2.0 build and rebuilt the databases from scratch - it is still ignoring the same folders in the TV section.
I’ve used FileBot to rename all 1,700 files to the format the TV Scraper is expecting to see - but it’s still failing to recognise these files. There were a few illegal characters in some files - which I found and got rid of - which may of thrown the scraper.
I’ve used WINScp to log on to the box and check the permissions of each of the folders in the filestructure and they appear to have the same system level access permissions on both the files that work and fail.
I’ve run the scraper again and its still dismounting the disk on the TV folders. Is there a max depth file structure limit, or max total path length limit that is being breached (like nesting seasons separate folders?)
I really invested in the Slice kickstarter for the polished product - that was hackable to play with Pi and restore as a media centre - but I’m doing more hacking trying to get it to work!
