Thanks!
Most of my questions were answered.
I should have known that if it runs Linux (I suppose the Enigma2 runs on OpenPli) then the possibilities are indeed endless. (but getting it to do exactly what I want will probably be endless too )
Most of the local tv-shows I watch are now available via free streaming services, so if I can get the streaming TV-apps (like VRT NU or VTM GO) to work on the receiver, it could double as an Android-TV player.
Do you have any other suggestions / alternatives I should look into? Or should I just order one and hope for the best?
