Use the NTSC-out spigot on the front panel of the Onyx. There is a
composite and S-VHS connection (I think). Use the vout command to
pop-up a NTSC-sized frame. Position this frame over the region you
want output and voila. You'll need to size your application to the
proper size since this option doesn't do fullscreen conversion. See
the vout man page for details.
