The unit replaces an older TechniSat receiver type MF4-S. The transition was very easy, the result very satisfactory. The picture was significantly better and above all, the recorder function is working properly. Just a standard USB flash drive plugged in and off you go. For an HD movie a 16GB stick was good enough and then you can put the file on the PC and so has re-place on the stick. The remaining functions are easy to use, typical TechniSat. Overall, highly recommended.
