It's difficult to say, because there are already differences between Wlan and Lan. In the end, it does matter who the provider is and how high the buffer time is set. Do you use SmartIPTV on the Sony or another app? Personally I don't see much difference between Mag, Samsung App and Android (Mi Box), all three run the SIPTV platform/app. All three have a good Lan or Wlan connection. I think the devices should have at least 35-40Mbit/s to run properly.
