Just adding to what has Abu said, I would install Open Atv 7.3 and just install the plugins you need. As said autobouquetsmaker comes installed with Atv and you probably need to install epg importer.Ive bought a new zgemma h11s, ive only ever had success loading wooshbuild on openatv 6.3.
Now i see h11s has no 6.3 build.
What are my options, has wooshbuild been sorted on later openatv builds as anytime i done this previously it always crashed and had to use 6.3
