-/* This is a list of what needs to be fixed:
- *
- * When the option: "Display full screen when dragging window" is enabled in
- * Windows display properties, the overlay surface coordinates won't be updated
- * (but it won't crash anymore ;-) I know where the problem is in the code, but * I just don't know yet of a nice way to fix it.
- *
- * When you move part of the video window outside the physical display, the
- * overlay surface coordinates are not updated anymore. This comes from the
- * directdraw UpdateOverlay function which doesn't like negative coordinates.
- *
- * For now, this plugin only works when YUV overlay is supported (which it
- * should be nowadays on most of the video cards under Windows)...
- *
- * The overlay doesn't use double-buffering.
- *
- * Port this plugin to Video Output IV

/*****************************************************************************
- * Preamble
+ * Preamble:
*
+ * This plugin will use YUV overlay if supported, using overlay will result in
+ * the best video quality (hardware interpolation when rescaling the picture)
+ * and the fastest display as it requires less processing.
+ *
+ * If YUV overlay is not supported this plugin will use RGB offscreen video
+ * surfaces that will be blitted onto the primary surface (display) to
+ * effectively display the pictures. this fallback method enables us to display
+ * video in window mode.
+ * Another fallback method (which isn't implemented) would be take the
+ * exclusive control of the screen so we could spare the blitting process and
+ * decode directly to video memory. This should theoretically allow for better
+ * performance (although on my system it is actually slower) but this is
+ * restricted to fullscreen video.
