MF playback app to demonstrate use of EVRPresenter; the error in the EVRPresenter code.

[vasilich-tregub]

The Usage section of the EVRPresenter sample is outdated, the instruction on a MF application does not work. I created a solution to demonstrate the use of EVRPresenter (see repository https://github.com/vasilich-tregub/MFEVRPlayback). The solution includes also a project EVRPresenter which is basically a branch of Windows custom EVR presenter sample. I found the bug in the master branch of EVRPresenter library, fixed this bug, and included the corrected version in my repository.
