MCI, playing an AVI, using my own window

I am using the Media Control Interface to play an AVI file.  I can easily open, play and close the AVI file.  By default the video plays in it's own window that is created on play.

This is all fine--but unfortunately I want to play the AVI file within my own window.  To do this, I have done the following after issuing the open command:

  MCI_DGV_WINDOW_PARMS params;
  params.hWnd = wnd.m_hWnd;
  if (mciSendCommand(m_OpenParams.wDeviceID,
                       MCI_WINDOW,
                       MCI_DGV_WINDOW_HWND,
                       (unsigned long)&params) != 0)
  {
    return FALSE; // some error
  }

This works... well sort of.  When the video initially displays, it appears fine.  But as soon as it begins to play, the video appears garbled.

My guess is I might need to handle screen updates or something.  Unfortunately I can't find any documentation or samples for this.

Thanks in advance.

When you say it appears garbled, does it mean the color of the video changes or the image changes or something else? Do you have your own color palette operation in your window? My program plays AVI files in my own window fine. I don't think you need to handle screen updates.

The following code was extracted from Video For Windows 1.1 Programmer's Guide.

The following fragment finds the dimensions needed to play an AVI file, creates a window corresponding to that size, and has MCIAVI to play the file in the window:

HWND        hwnd;
MCI_DGV_RECT_PARMS mciRect;

// Get the movie dimensions with MCI_WHERE.
mciSendCommand(wDeviceID, MCI_WHERE, MCI_DGV_WHERE_SOURCE,
    (DWORD)(LPSTR)&mciRect);

// Create the playback window. Make it bigger for the border.
hwndMovie = CreateWindow("mywindow", "Playback",
                         WS_CHILD|WS_BORDER, 0,0,
                         mciRect.rc.right+(2*GetSystemMetric(SM_CXBORDER)),                         mciRect.rc.bottom+(2*GetSystemMetric(SM_CYBORDER)),

                         hwndParent, hInstApp, NULL);

if (hwndMovie){
    // Window created OK, make it the playback window.

    MCI_DGV_WINDOW_PARMS    mciWindow;

    mciWindow.hWnd = hwndMovie;
    mciSendCommand(wDeviceID, MCI_WINDOW, MCI_DGV_WINDOW_HWND,
                   (DWORD)(LPSTR)&mciWindow);

}


The following fragment shows how to display the window using the command message interface:

MCI_DGV_WINDOW_PARMS    mciWindow;

mciWindow.nCmdShow = SW_SHOW;    // set command - see ShowWindow()
mciSendCommand(wDeviceID, MCI_WINDOW, MCI_DGV_WINDOW_STATE,
               (DWORD)(LPSTR)&mciWindow);
