I use osmc on a rpi2 at the moment and one of my main uses is to display home videos. The titles just apear as a list or as a thumbnail captured from the footage. It would be great if they could be listed in the same way that commercial movies are within kodi. If it could be made possible to insert a cover art jpg and a synopsis the appearance would be vastly improved and would match that of the movies and tv shows.
We believe this is a Kodi issue or a specific Kodi function and as such you should look at addressing the issue there. We are unable to resolve your issue. If you do believe that this is an OSMC specific issue, please let us know.
