Remarks
Loads a video from the specified file converting the audio track to Mono for use with EAX effects.
Video loading and rendering is performed through DirectShow so, in order to load a certain video format (like MPEG, MP4, AVI, etc.) the specific codec must be available on the target system or calls to this method would fail. One of the best packages containing most audio and video codecs for DirectShow is K-Lite Codec Pack and can be downloaded for free from the following link.
IMPORTANT NOTE ABOUT CODECS AND WINDOWS 7: When dealing with Windows 7, also if you have installed K-Lite and configured ffdshow to manage a specific format (for example the MPEG-2 format or the H.264 format used in some MP4 video clip), DirectShow will continue using the default decoder named "Microsoft DTV-DVD Video Decoder": the quality of this decoder is quite poor and doesn't support the VMR-9 video renderer used for mixing/blending video clips so a call to this method could return back an error when the involved player has been added to a video mixer through the VideoPlayer.AttachToVideoMixer method; inside Appendix B you will find a few guidelines that could be of help in order to manage DirectShow configuration through K-Lite provided tools.
