Hi Anthony,
at the end of your email you ask for the saa7111 stuff.
The nt1003 is just a digital chip. To grap the analog video signal,
you need an AD converter. And that is the saa7111, which is kontrolled
by i2c. The tuner we have in our miro or hauppauge usb TV boxes is used
to receive the HF signal via antenna. But if you have the video base
band
signal from an other source (SAT-receiver, VCR...) you do not need it.
Can you find out what AD converter the Belkin is using?
Cheers
Joerg
P.S. I'm on holiday from 15.09. to 25.09.
