The Media Player normally understands automatically which orientation the Display uses for presenting contents. This information comes from the Display to the Media Player.
But sometimes there are hick-up's with the communication between the Display and the Media Player.
A stretched content indicates that there is a problem with the orientation. In those cases check the Display orientation from Valotalive at the Displays tab.

You might need to adjust the Display settings with a remote control as well.
