Ok, 

After a little research, I decided to test the card in a win2k box and
make sure it was good.  Thus I downloaded sagetv and tried the card with
it.  I got the card to work, however, I noted I got similar static when
I initially switched to a different tuner.  It went a way as soon as I
choose to view a channel.


Thus I am thinking that one tuner is not being tuned to a channel
correctly.  So how do I force this?
