I (also twin) possess many years of experience with TechniSat receivers, it struck me rel. easy for me to decide on the S3 Isio. The present Anschlussmöglichkleiten are "top", the installation is very easy and works almost by itself. Per enough HDMI one cable for everything. The then geziegte image will still need "test basis" to 1080 p -the be switched result I can only describe as "brilliant", respectively. The sound is another story. Of course DOLBY must be activated and a genuine Digitals "language" actually the sound format Bitstream. But on the (optionally with HDMI / Coax) angeschlosenen Yamaha Receivers arose repeatedly short audio dropouts - tentatively switching the sound "Language" on PCM came to the rescue. But PCM is an analog, not digital audio transmission and connected receiver does not recognize so, whether and to what DOLBY Fornmat the sound is transmitted. First Receiver exchanged, the replacement device much rarer dropouts, but as usual. Consultation with TechniSat - information: "Bitstream can be too loud, should really only be used for Scart connection". Hello ?! The difference between the two devices already shows that there is something wrong in the factory - and the information is surely ... technical nonsense. My other (older) TechniSat receiver transmits error-free bitstream. Therefore, two points from this otherwise great device.
