need to redo bouquets
not sure for what you need it at all ?
there are "Tags" at Tvheadend that are basically replaced it, they are also supported at Kodi
to allow dlna clients access the streams from tvheadend (DVB-T,DVB-S) !
why not use an htsp client or Sat>IP client ? Tvheadend Client works awesome at Android for example
btw you can also run tvheadend instead of minisatip and activate the sat>ip server if you need
in the end same result ofc (minisatip has better performance)
