And it worked. Great. Just had to add a "/" infront of the path with sqlitebrowser, so linux could understand the folder-structure.
I'm missing my thumbnails, which i have lying in an old folder, but i guess i have to settle with the recordings being a part of the DVBLink "TV Recordings" now. Thank you for "sparring"
I could add a function to leave the recorded files where they are and import the metadata but DVBLink won't be able to play the media files. The media files has to be in a specific directory which is specified in the DVBLink settings. If you already have the media files in that directory, then I would recommend moving them out to a temporary directory and then run the importer with the move setting.
