+Windows XP DirectShow Sample -- VMRMix
+--------------------------------------
+
+Description: This application shows capabilities of the new
+    video mixing renderer (VMR) that is the default video 
+    renderer in Windows XP.  In particular, it demonstrates 
+    how to use the VMR in a mixing mode with several sources, 
+    how to apply a bitmap image with a color key over the video, 
+    and how to take advantage of the IVMRMixerControl interface 
+    to manage source and destination rectangles and alpha-level 
+    for each media stream.
+
+Usage:
+    Upon initialization, VMRMix asks the user to specify a 
+    media folder that contains at least two valid media files, 
+    after which it loads media settings from that folder.  
+    The user is asked to specify playback options: 
+    number of source files, size of the playback window, and 
+    whether to display a static bitmap image.  When the user 
+    clicks on the 'Play' button, a new window appears to mix 
+    the selected streams.  The demonstration lasts until the 
+    longest media file reaches the end.  You can interrupt the 
+    demonstration  by closing the playback window.
+
+Troubleshooting:
+    This application was originally created as a stress test, 
+    so it uses more system resources when displaying a maximum 
+    number of streams and when using "full-screen" mode.  If 
+    video is freezing or slows down, try selecting fewer sources 
+    and turn off the "full-screen" option.
