Currently, the Graphics DDK only support video capture when the capture
device is built into the graphics adapter, (like the ATI all-in-wonder).
There currently exists no specific driver framework to support a
standalone capture device (although one is in development).
You would need to write a full resource manager type driver, (although
you might find name_open()/name_attach() to be sufficient).
Alternately, you could just write a library of routines to drive
the wintv card, and link your app with them; the only drawback being
that the app will have to run with root privileges.
So basically the Graphics DDK is a red herring for what you are
trying to accomplish.
