+DirectShow Sample -- PlayWnd
+----------------------------
+
+Usage:
+
+    playwnd <media filename>
+
+Description:
+
+    This sample is an interactive audio/video media file player.
+    It uses DirectShow to play any supported audio or video media file
+    (MPG, AVI, QT, WAV, AU, SND, MID, etc.).  The video will appear in
+    a window on the screen, and you can use a mouse to move the window.
+
+    If the media has a video component, PlayWnd will read the video's
+    default size and adjust the player's client area to allow the video
+    to play at its preferred default size (taking into account the size of
+    caption bar & borders).
+
+    You may mute the audio by pressing 'M'.  You may toggle full-screen mode
+    by pressing 'F'.  You can pause/resume playback with 'P' and stop/rewind
+    with 'S'.  To close the media clip, hit ESC, F12, X, or Q.
+
+    If the media is audio-only, the player will display a small default window.
+
+    You can specify a media file as the only command line argument:
+    	Ex:  playwnd \\myserver\mediafiles\video\sample.avi
+
+    If no file is specified, the application will automatically display the
+    Windows OpenFile dialog so that you can choose a file.
+
+    Use the menu bar or the close button to exit the application.
+
+
+Accessing media files
+
+    The media file may exist in your hard disk, CD-ROM, or on a network server.
+
+ If the file is on a network server:
+    You may read a media file from a network server if you provide the full URL.
+    For example, "playwnd http://myserver/mediafiles/video/myvideo.avi" will
+    read the file from the server into system memory.  This approach will fail
+    if the media file is too large to fit in memory.
+
+
+Limitations:
+
+    This sample will only render media files that are supported by the
+    DirectShow subsystem.  If you attempt to play a video (AVI, QuickTime, MPEG)
+    that is encoded with an unsupported Codec, you will only see a black
+    screen or no visible change to the display, although you should hear the
+    associated audio component if it uses a supported format.
+
+    This sample will not play .ASX files.
+
+
+User Input:
+
+    Simple user input is supported through the keyboard or through the 
+    application's main menu bar.
+
+    Keyboard                    Action
+    --------                    ------
+    P                           Play/Pause toggle
+    S                           Stop and Rewind to beginning
+    M                           Audio mute toggle
+    F                           Full-screen mode toggle
+    Quit to menu (closes file)  ESC or Q or X or F12
+
+
+NOTE:  This sample enforces a minimum window size (currently 200x120) to prevent
+window problems when small videos are resized.  You may not resize a video to play
+in a window smaller than the defined minimum size.
