VIDEO_TS and The TVDB

I'm struggling with getting The TVDB to scrape ripped DVDs with multiple series in a single VIDEO_TS

As an example, I have the ripped the four Blackadder DVDs to VIDEO_TS folders, and have tried the following layouts

Blackadder\Season 1\The Black Adder\VIDEO_TS
Blackadder\Season 1\VIDEO_TS
Blackadder\The Black Adder\VIDEO_TS
The Black Adder\VIDEO_TS

However none of these appear to work.

The examples on https://kodi.wiki/view/Naming_video_files/TV_shows shows DVD and BD layouts for when there is a single episode per ripped disk, but do not appear to have an example for when there are multiple episodes on a single ripped disk.

Do I need to re-rip each disk and extract each episode ? or is there a way to keep the original VIDEO_TS format ?
