There was an issue in early betas of 1.19.5 and that was fixed in 1.19.5.3035
See release notice Plex Media Server
- (DVR) Server would fail to load program data for certain XMLTV guide sources
Aside from that, there are issues with very large xmltv files
I would need server logs with debug logging enabled and logs captured when the xmltv guide is not loading after a guide refresh or DVR setup. I may also need the actual xmltv file
