Live TV - no channels displaying under "Shows >"

The two that aren't working have two titles instead of a title and sub-title. But the first example also doesn't have a sub-title. The one thing that the first example without a sub-title has is a different episode number system. "xmltv_ns" vs "onscreen". I wonder if that is also a factor.

According to https://github.com/jellyfin/jellyfin/pull/12398, the fix in v10.9.10 assumes "that if the program has an EpisodeNumber then it is part of a series." To me this implies that all is needed is data within the episode-num system tag, and for recordings to be scheduled this data needs to be different than any previously scheduled/recorded episodes. I just had another look at my two "not working" examples. I see they have duplicate title tags - it is possible that this is confusing Jellyfin. I will have a go at manually removing the duplicate title tags to see if this resolves the issue.

After looking at the latest Jellyfin server code, the best approach to ensure that the "record series" button shows after refreshing guide data from an XML file is to make sure there is an episode-num element with attribute, system="xmltv_ns". In this particular "system" value, the episode number is always after the first ".", and the first "." is important even when there is no season. For example, episode 5 for a program that has no "season" would be, &lt;episode-num system="xmltv_ns">.5</episode-num&gt;.

The "onscreen" system case (i.e. episode-num system="onscreen") is completely commented out, FYI. An empty "system" or missing the system attribute is also ignored.

Reference the Jellyfin.XmlTv..XmlTvReader method, ProcessEpisodeNum, for details on determining the episode number.

Reference the Jellyfin.LiveTv.Listings.XmlTvListingsProvider method, GetProgramInfo, for details on how "IsSeries" is set.
