It’s just a basic DVD player . It says it plays dvds and video cds that conform to compact disk standards . It cannot play non standard shaped disks (like card, heart). Playable formats mpeg1, Jpeg, mp3, wma , wav .....
I don’t know if it plays mini dvds , I’ve never seen one . Maybe you could transfer the video to a laptop then copy it back to a standard dvd if you can’t find a player .
