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
