I’m experimenting with a Fire Stick based app.
It’s decent in concept, but doesn’t work so great, you end up with buffering, synch issues and a iffy picture.
I’ve tried signal boosters but suspect the app itself has quite a heavy overhead, have skys full fat broadband with no problem streaming anything else, either in the house or the garden.
Is probably sound if wired to the router, but fucked if I’m rerouting cabling etc to find out.
In short, close but no cigar.
