Yes, you can receive SRF via SAT with this TV as it has a DVB-S2 tuner. You no longer need a special card as long as you connect a satellite dish and a cable to the RF/Sat input. Simply start the channel scan in the DVB-S settings.
According to my research, the difference is that the AEU model is the European version and the API model is the international version. We offer a 2-year warranty for both models.
