I have watched my Directv DVR play list on my Windows 10 laptop.
Step 1. Emulate a supported device. I used Nox & Android.
Step 2. Install Directv App. And Bob's your uncle.
This is only a work around, and it is a long way from bullet proof.
So why did I say (I have watched)? I just had to reinstall everything.
This time the Directv playback is high speed, like fast chipmunks.
Both live and DVR playlist. I set the FPS in Android from 60 to 40, no change.
I have deleted the App & reinstalled it, No joy.
I just want to watch what I have on my DVR!
Give it a try. It just mite work for you.
