Hi,
We have been successfull in transferring video straight into the
video frame buffer of my PCI graphic card. The end result is
a cool tv 8)
There is not much to do in terms of PCI-TO-PCI transfer.
In my case, I just loaded up the physical address of the video frame buffer
to the video capture board registers.
I am not familiar with PCI ethernet cards so I am CCing hackers.
Cheers,
Amancio
