cannot install tvheadend on libreelec 9.0 build

  • Hi, I have installed Milhouse 9.0 build with a view to getting both tuners working on my wintv-dual, however i am getting an error message ... "The following addon will not be installed" "os.libreelec.tv" and under that it says "not available".

    Do i need a specific version of tvheadend? Have i missed a step in the process somehow? I would appreciate any advice on how to overcome this, I have tried searching the error but am not sure i am phrasing it correctly as i am not finding any pertinent results. Thanks
