Well, according to a customer comment on Newegg, that
item is only for an ATI card (you are using an nVidia
one), and that comment also states that you need to
use the ATI DVD player software in order to play a DVD
back with it.

Therefore, I'd say that there's something within the
circuitry of that adaptor that the video card can
sense, and with the proper software, tell the video
card to send out component data.  This is likely to be
Windows and ATI specific, and therefore not likely to
work for you.

If you can't see even the BIOS screen on your TV set
through the adapter, then there's a problem, since it
should be sending out that basic screen through all of
the inputs via regular BIOS calls (it's when you load
the OS that you need specific support in the driver).

Try a transcoder, like the Audio Authority 9A60, it
seems to be pretty popular on the list.  Try reading
this info from Jarod Wilson, who uses one and
documented his experiences:
