I have the Amiko Mini 4K UHD Combo tuner. When I turn on NASA UHD, the image does not appear, but a black screen with strange artifacts, instead of sound, there is a robotic whirr and the tuner restarts on this station by itself. In the case of Canal + UHD and Evénement Sport 4K UHD, the picture works normally but the sound does not work, although according to the flysat.com list these stations have AC3 sound, not AC4. On other FTA 4K stations, the picture and sound are normal.
Does your Amiko with 4K also have such a problem with the NASA UHD TV station and the sound on Canal + UHD and on the Evénement Sport 4K UHD does not work either?
A question for owners of other 4K tuners: is there such a problem in your tuner with NASA UHD and sound on Canal + UHD and Evénement Sport 4K UHD?
