I want to set up epg123 as my guide provider using xmltv. I just tell emby where to find the xmltv data in my epg123 folder?
What are the advantages and/or disadvantages of this vs the native guide that Emby imports directly from SchedulesDirect?
What "holes" are in the guide in Emby when using xmltv?
If using the XMLTV generated by EPG123, yes. All that would be needed is to direct emby to the epg123 folder and the epg123.xml file.
For advantages/disadvantages ... I would say EPG123 has more safeguards in place to handle SD JSON server problems that will avoid any corruption of the guide we've seen in the past on emby. I know the issue has been addressed, but don't know how complete it is or how successful it was. I also don't know how much of the XMLTV data gets pulled into emby (3 days? 7? 14? certainly not the 21 that we can pull). Another advantage of XMLTV by EPG123 is the ability to limit the channels downloaded ... not something currently available in emby let alone the custom numbering or listings.
I've shown some differences above that point out some other advantages/disadvantages.
I would also say that EPG123 has a much better channel logo selection and manipulation as well as better artwork selection for both series and movies. So a plus for EPG123 XMLTV but can easily be addressed in emby coding.
