[vtkusers] win32videosource drivers

[David Gobbi]

Hi Mark,

The vtkWin32VideoSource expects the video driver to provide it with 
uncompressed video format.  The "dvsd" fourcc code indicates that the 
video driver is providing a compressed digital video format.

If you call the VideoFormatDialog() method of your vtkWin32VideoSource 
object, it should pop up a dialog box that you can use to select between 
all the different formats that the driver supports.  Every driver that 
I've seen provides at least one uncompressed format.  These will usually 
have codes like UYVY or RGB.  Also, uncompressed greyscale video should 
definitely work.
