I stand to be corrected Mike , But , with IPTV-Editor , under "Auto Updater" , you set it to upload changes from supplier , iyou can set it to upload changes to the categories that you are using and or the categories that you have removed. Also set it to upload any new categories/groups. My main list comes like most of them with I think 233 with categories/groups , I have it trimmed down to 28 groups (1325 channels) as well as all the editing of logos, channel names etc and adding EPG to some of the malaysian,thai,hongkong sports sections, together with completely removing the VOD and Series. Can't expect my supplier to do all that .
