I am not too familiar with Apps but want to jump in to them some. What is the best way to launch an App, thru DISH's DVR apps or use the TV apps? For example, if I want to watch a Netflix 4K movie would the picture quality be better thru the 4K TV (Cat5 connected) Netflix app or thru the Hopper's Netflix app? What about the DVR functions, full or partial functions thru the TV or DVR? What about a Slingbox, is it better to use apps thru it? I have a Slingbox 500 attached to one of my HWSs. Thanks for any help.
