Add XMLTV Data To JellyFin From HDHomerun

I have a NAS on which I have installed Jellyfin.  I chose Jellyfin from the usuals, because I didn’t want to pay for another streaming service (if you have to pay to watch tv, it might as well be a streaming service).

Anyway, jellyfin automatically detected the HDHomerun (2 tuner, old) connected to my network.  And while I could watch live tv via the Silicondust/HDHomerun app, the ability to see all of the tv programming on Jellyfin was just too enticing to pass by.

Turned on logging in scheduled tasks.  Errors, added group docker with admin privileges.

synology task scheduler run result interrupted – https://community.synology.com/enu/forum/1/post/150119?reply=467768

sudo chmod 666 /var/run/docker.sock – https://stackoverflow.com/questions/48957195/how-to-fix-docker-got-permission-denied-issue  chmod 666.

changed save directory web folder – issues with writing outside the web folder

then setup user permissions in nas – control panel > shared folder > web > edit > permissions > system internal user (drop down) > jellyfin initial user (during setup) > give it read access

cron job to get tv guide xml data:

Set up above script as a cron job.  Point jellyfin to storage location for tv guide xml data and you’re done!  Sorry for the scarce details, as I did this quite a while ago.  Personally, I have gone back to using hdhomerun’s recording control, but it’s still nice to see the tv guide data in Jellyfin.
