I am looking for a twin tuner box that will record to my NAS and allow easy playback onto tablets/phones (Android). I have seen recommendations for the AX HD61 box which looks great, although I have some questions about how this or similar boxes work....

These can have a sky like EPG put on to make them user friendly, is that correct?
Is there a series pass option?
How can I playback the recordings - can they be played back via an Android app? (Plex or Kodi?)
I have a cheapo Android box with Kodi on it - can the recordings be access via that?
