it doesn't work!
Italian Terrestrial will be DVB-T2... but H265. Only the DM800HDse/V2 (and DM820, DM7080, etc) support this DVB-T2/C Hybrid tuner, as the driver support it. All these boxes are H264 and not H265, so only DVB-T2 MPEG4/H264 will work, not the H265 channels. DM8000HD driver doesn't support the Hybrid DVB-T2/C Tuner (In fact it could be a nice gift to release a new driver supporting that Hybrid tuner, for all the owners of the DM8000HD highly expensive box, as the DM800HDse supports it).
Thank yous two so much.
It's so surprising to me that my old terrestrial tuner Alps is fit for next HEVC H.265 codec: actuallly I can watch some test channels broacasting with that codec. Unfortunately italian channels are going to swap to DVB-T2 and that tuner won't work anymore. It would be really nice if new drivers will come. My old receiver is working as a charm and I'd love to keep using it even if I bought a DM920.
