[improvement] Imperfect frame cadence

[tamodolo]

For 120Hz native screens the players can't actually go beyond 60Hz. This is a problem for video content available on CR as it's 99% 24fps content.

Playing 24 fps video in 60Hz mode result in 3:2 pulldown method being aplyed as a way to smooth the video playback. For 60Hz screens this is the solution to use but for 120Hz were you can just play 24fps as is and obtain even frame cadence. For that reason the actual solution is not good.

Solution: let the app works on 120hz mode when that's available.
