            // Create the interop host control.
var host = new WindowsFormsHost();
// Create the ActiveX control.
var axShockwaveFlash = new AxShockwaveFlash();
// Assign the ActiveX control as the host control's child.
host.Child = axShockwaveFlash;
// Add the interop host control to the Grid
// control's collection of child controls.
this.MainGrid.Children.Add(host);
axShockwaveFlash.Location = new System.Drawing.Point(0, 0);
axShockwaveFlash.LoadMovie(0, @"C:\player.swf");
axShockwaveFlash.SetVariable("quality", "Low");
axShockwaveFlash.ScaleMode = 0;
axShockwaveFlash.AllowScriptAccess = "always";
//axShockwaveFlash.FlashVars =  @"file=C:\barsandtone.flv" + 
//&autostart=true&fullscreen=true&controlbar=none&repeat=" +
//"always&stretching=fill";
axShockwaveFlash.CallFunction("<invoke name=\"loadFLV\" " +
    "returntype=\"xml\"><arguments><string>barsandtone.flv</string>" +
    "</arguments></invoke>");
axShockwaveFlash.Play();

            If you want to use DirectShow, you must use WPFMediaKit.
With http://www.free-codecs.com/download/K_lite_codec_pack.htm it will be ok.
