If that's the case I suggest you invest in a VPN app (about €50 a year) and use the various player apps. Change the location to suit the UK ones and you can switch to here for RTE and Virgin players.I have the basic TV package....about 20 stations including RTE, BBC, Channel 4 etc. (over 20 years now).
Edit note: If your telly is as old as your tv box this may not be an option
