I've changed that to inprogress_tvshows.xsp (and I double checked that my playlist is named like that) but when I start kodi I only get a black screen now :-\
sounds like an error in home.xml
<param name="content_path" value="videodb://inprogresstvshows"/>
<param name="content_path" value="special://skin/playlists/inprogress_tvshows.xsp"/>
