Have you configured your Shield TV for 50Hz output. By default it usually runs at 59.94Hz (which will be even worse) and it doesn't refresh rate change automatically in most players (it does in Kodi and SPMC)

NOW TV
I recently purchased a NVidia Shield, which allows you watch NOW TV through the Chromecast Ultra add-on and the 25fps issue is really noticeable. I watched Nat Geo Wild and you could see where the lack of frames per second shows on fast scenes which is similar to what happens when you watch sport on Sky Sports.
