I have just gone back to putting my sub on Zgemma H7s as I had real problems with EPG at the time of crash so moved to Firestick,
@Baz helped me and to be honest I couldn't believe how simple it has become with Xtremity and Xclite, I did use Jedi before and @Dsayers script was a godsend no script is required for Xtremity and Xclite!
