does the related video has subtitles?

also do you have the same issue with the videos without subs?  

now that you mentioned it, I checked with ver -1.2.10, only videos with external subtitles files gives the error  "_get_item_play_url() takes at most 5 arguments (6 given)" , movies without subtitle files plays just fine ...   

Do you play it via exported strm files or just inside the addon?  

the issue happens in both, strm files and direct from the addon
