Sorry for my English. That's the same frame in the player-case EVR, as well as a splash pro. Note - in EVR Compass round due to the nonlinear stretching.

Nonlinear stretching to the whole display area. You can look in the Windows Media Center. Or in any case with EVR set IMFVideoDisplayControl.SetAspectRatioMode(5)

You're the best! But do please nonlinear stretch, as in the EVR. To view the old 4:3 videos on the new monitors.
