okay if my research is correct
FiOS is a verizon thing that you get
im assuming its your cable tv
you should just be using coax cable (standard cable tv line)
in which case you just plug that into the digital coax in on the back of that card
(they are labled)
and then have windows do all of the heavy lifting
i have insight at my house with a cable box and BB inet
i just have a coax cable conected to my card and it works like a dream
i just need to amp the signal because i have a splitter installed in there
but yes it should work w/o another box
if it doesnt then i have mislead you or something like that
if you are getting tv from the air (bunny ears)
then just plug the bunny ears into the card
most of the newer antennas are using a coax cable
so that should work as well
i have alot of people asking me how to hook up their converter boxes (at work)
i work at the shack
and all of the antennas that we sell use a coax cable to connect to the tv
if you have an older one
then just buy a new one for 11 or so
and that should work providing you are getting a strong enough digital signal at your house
if not
then get an amplified antenna
and it will allow you to get the weaker signals that you might not get other wise
if you have any more questions dont hesitate to ask
later
