DirectTV account/ streaming app

There is only one app now and yes you use that app to stream most of the DTV sat subscription channels to a device that is compatible with the app. 

AFAIK DTV has not add streaming from the DVR to the app yet but some posts say they can, but most channels in your channel package can be streamed to the app..

Sports and local channels are some of the channels that may not be streamable from the sat subscription to the app.

If I am comprending Shannon's response correctly, then I am able to use my Direct TV account (satellite) at my second residence to stream Direct TV service using the streaming app. (Forgive my ignorance of all things dealing with this technology we have today. I am of an age that all this stuff is "Greek" to me. I just do the best I can if there is not a grandchild around to help.)  Any help with how I accomplish this is appreciated. 

Most of the DTV sat channels can be streamed to the app.  There is no longer what was called the DTV streaming app it is just called the DTV app.

Thanks
