2 football teams at the same time?

Not possible. 

Unfortunately DIRECTV STREAM does not have that option.

Normal DirecTV (the satellite service) has Picture in Picture (PiP), a split screen option on their main Genies (HR34, HR44, HR54 / HR54R1). No other box has it, so only one TV in the home can use it.

Mentioning in case this thread is stumbled upon from those of either service.

Yes, you can. Depending on the receiver you have, you might be able to set up Picture-in-Picture to watch two programs at the same time. You need to turn on PiP as follows:

- Press INFO on your remote control.

- Select PiP.

- Select On and Side by Side. The current channel you're watching appears on the inset screen.

Jhon, there are no DirecTV Stream devices that support PIP. 

Do you think the reps don’t see that questions are posted to Stream rather than satellite, or do they just not understand that those are different things?   Or maybe they don’t care?  Because their answering Stream questions with satellite answers is ubiquitous. 

All too often the support reps don't actually read our previous answers. This question was already answered, so there was no need for them to respond. 

Still doesn’t explain why they so often provide satellite answers to Stream questions. 

I agree. Even the article refers to a "GENIE". Amazing!
