video mp4 and adding to playlists

Wasnt DDJ RZX designed to work with videos?  I cant even add videos to a video play list.  I am sooo fed up.  $3000 tables and i cant do a simple video play list.  Serato had no issues.  does anyone know how to map the DDJ RZX to serato like this guy did?  https://www.youtube.com/watch?v=9_u-Tiw_fyg

to have to do 2 seperate playlists for videos and mp3s is asinine. Bring back Serato.
