I'm curious how the additional elements affect the EPG in TvH. Can you explain a little what these are for and how I would use them?
Basically - depending on what skin you are using to display your epg...you may want to see additional info but the skin doesn't have the option to show it. For example, the Confluence skin doesn't show the original air date of an episode in the epg screen. You have to go into the epsiode info screen to see that.
If you want to see the original airdate in the normal epg screen, you can use the "append xtra details to the program description" option. Then on the "xtra details order" tab, you can add the plot and original air dates to the list. You can even add a bullet or hyphen between them. Or add a line break between them and the original air date will appear below the plot description.
All of the items that you add to the "xtra details order" tab will be written in the plot description field in the order you select. This modifies the original plot description when writing the xmltv.xml file that tvheadend reads. Then this info will be displayed in your skin anywhere the plot description is normally seen.
You can always turn it on, try a few items to see how they look, adjust or turn it off if you don't like it!
Please keep in mind that depending on how you have your guide data refresh setup in kodi, you may need to reboot or even clear guide data in order to read in the new info. Also, once you make the changes to the xtra details list, you need to rerun the grabber (which you can trigger in tvheadend) to get the updated xmltv.xml file to write out.
If that was confusing - please feel free ask any questions!!
P.S. I (and Schmell) are working on an issue with Spanish language (and other) characters. I think I have a fix, but can't test it until I return home this weekend.
