i have just got a message from Geniatech Europe.
The main reasons for the technical EPG problems are technical server problems which last longer than expected.
Normally, such a faulty server would have been temporally replaced and repaired.
Netstream4Sat is a reliable SAT>IP receiver which works fine for me in a multi-Sat environment. So no Geniatech bashing on hardware - EyeTV4 and the paid EPG is the problematic part.
If you have Netstream4Sat you can use any Sat>IP app. There are a couple of apps in the AppleAppStore - look after the phrase SAT>IP or Sat over IP.
…and EyeTV4 is still working on Intel Macs for most people but without paid EPG.
