To help reduce loss of video there are recommendations for hardware decode, some sat on and other off. Is there a recommendation for different controller versions, A vs B. How about for various iPads, in particular an iPad mini2 and a mini4? I'd like to give my brother a P3P, controller 300A with a iPad mini2 and my own P3P being on a 300B and mini4. Would the settings be different for the two set ups?
