I have always wanted a reliable dual tuner satellite STB, but never have found one that properly managed motor control and timed events. If it properly managed the dual DVBS2 tuners, I would lean towards that configuration.
The ATSC option would need to have an exceptionally sensitive tuner and EPG XML database integration. Otherwise, it will just be another unused ATSC STB tuner.
Hard for me to get excited over a product announcement of an untested STB. Seen too many manufacturers provide STB samples that are big on promises and specifications that end up being worthless pieces of junk!
My personal Amiko A3 continues to perform without any problems. It is running .72 and I don't load any other apps. I continue to enjoy the exceptionally sensitive tuner that catches almost any feed and the reliable daily recording of the network feeds.
I strongly disagree with the suggestion that the Android OS is the problem with multi media STBs. The loading of other apps and allowing automatic updates cause conflicts and database errors with the Android STBs and tablets that I test and own.
