Surface Pro 4 DRM broken

My win10 Surface Pro 4 can no longer play DRM channels.

Diagnostics turned on the App and on the Prime.

As a point of reference, DRM channels are working fine on my Win 10 Surface Pro 6. I'm running HDHR app version 20190205.

Thanks for enabling diagnostic information.

From the error there are two likely causes...

1) Cached information - try uninstalling the HDHomeRun app and reinstalling from the store. This will wipe all cached information.

2) Round trip time check - it could be that it is failing the round trip time check. To confirm it really needs a wireshark packet capture to be run on the tablet while you tune a channel. If you choose to install wireshark and run a capture recommend not installing the USB driver, only WinPCap.

An uninstall and reinstall seemed to do the trick. I now have my DRM channels back. Thanks!
