0x91d70001 4k disc

I had the exact same error code (0x91d70001) when trying to watch my new "13 Hours: The Secret Soldiers of Benghazi" 4K Blu-ray, no other 4K titles (that I tried) were similarly affected. The method of ejecting the disc, unplugging and then
re-plugging the HDMI cable, before re-inserting the disc did work for me. However, to fix the issue permanently, I discovered that performing a full shutdown down of both the console and TV worked, so whether it was a HDCP issue of some variety is unknown.
Also, the issue with the 4K Blu-ray had persisted for almost a month before I tried the full shutdown, so I wasn't just hitting the issue on a bad day. Your mileage may vary but I hope this can be of help to someone.

I have the One S. I have a dozen other UHD Blu-rays working perfectly, but Deadpool fails to start with the error 0x91d70001. The disc was replaced by the store but even the new one fails, so it's not the disc.

oh ok good! try in-install/re-install of the Blu-ray app.

You could also try both of these suggestions.

Hard reset by holding the power button down on the front of the console until it turns off then unplug everything for 5 minutes then plug it all back in and try again or...

a console reset by going to settings, all settings, console and updates then reset console and choose to keep everything then your console will reset and you will sign back in again then once your back at the home screen try the Blu-ray again.

Hey there
batmax9011,

Thanks for reaching out about the issue here.

I can totally see how not being able to watch your favorite flicks could be frustrating.

If this is happening persistently with the Blu-ray player app, I would definitely try following the steps outlined in our

Xbox One Game Freeze Solution for it.

When you get a chance, give the guide a try and let us know if that helped with the problem.

Thanks for reading!
