Don't worry shawl_who bro,i don't know much details about tp & etc.,but i think 1 4k channel equal to above 2 hd channels,it's means adtv have lots of space for channel additions & i hope adtv add many sd & hd channels in 2016,If adtv launch the 4k stb with include recording features mean i will buy,but if d2h first add the recording features in 4k stb means i will go for d2h
