- Specify video folder with subfolders for ripped DVDs/Blu-Rays
- Display those subfolders while browsing with DLNA client
- Display the playlist when selecting the subfolder (as is displayed now with only one DVD/Blu-Ray)
Maybe you could scan all DVDs/Blu-Rays in advance to build the playlist-database to save time as an option.
BTW: Where can I order my key for MakeMKV?

Thanks,
Arne
