But this thread is about tv boxes, not what app you use. Specifically, I am concentrating on boxes that will stream Netflix in full HD, and that's a short list.
While checking out the various boxes I found one that includes a tuner, so now I've set my sights even higher, looking for the perfect God box that will steam Netflix in HD and also record OTA.
So far this is ash extremely short list: WeTek Play 2 and Xiaomi Mi Box, running Nougat (7.x) and equipped with a USB ATSC tuner.
The WeTek box appears to have a single tuner (cannot record/watch multiple channels). For the Mi Box the officially supported tuners are the same (one channel at a time). I find a Hauppage tuner that is dual, and it should work. But it's not cheap and I still don't know if tuner support in nougat works with dual tuners.
