i know that play<>record, and i wrote my last phrases not in good english, sorry.
anyway, for me a recorder machine has to record anything that it sees in his input, and record it using one from his personal methods, so if a signal H.264 comes at HDMI input, than the recorder machine has to record in one of his codec implemented, for example H.265.
For example, now in Italy there is not H.265 into signal television, isn'it ? so, DUO 4k SE can't record nothing ???
PS. i don't want to convert files in the HDD from 264 to 265, but i hope that i can play a bluray disc outside (in other standalone reader) and via HDMI in i can record this bluray into H.265 files. With the same resolution, or at max of H.265 can do
