if Kodi doesn't resume your videos

You can try adding in .kodi/userdata a file named «advancedsetting.xml», whose content is something like:

 <advancedsettings>  
 <video>  
 <playcountminimumpercent>95</playcountminimumpercent>  
 <ignoresecondsatstart>60</ignoresecondsatstart>  
 <ignorepercentatend>1</ignorepercentatend>  
 </video>  
 </advancedsettings>
