Not sure what country you are in but they removed the free supply of episode guide data for some places in July, see this link. Here in Australia it is no longer but fortunately this XMLTV file can be generated with some fiddling, depending on your fiddling prowess or maybe someone has done it already on the forum. Search for your country and EPG to find out. For us here in Australia yes the same thing happened so you pretty much have to delete your DVR out of Plex, find an EPG source that you can update daily or weekly into your computer and all may be ok. Check this Plex Aus EPG for some tips.
