Awesome that the playback works for you now

And you can probably find something else than windows media center if you can't use your old key.
In my opinion, windows media center isn't the best solution.
I just use kodi on the regular desktop with a flirc and harmony remote that controls everything for my media center. Hope you find something that works for you! And try to enjoy the 4k

Unfortunately with my Cable Companies archaic "DRM" policies, WMC was the only option in order for "Live TV" until some other company comes out with another solution.....

Great that you got it sorted

Yes, thanks to people like you. However, fixed one issue (4K playback) and broke another (No LiveTV) LoL
