Around here we seem to like Hauppauge's Bt848 cards they have proven
to be reliable and reasonable priced.

fxtv has two modes of operations :

1. capturing frames to a buffer then using xputimage to display the
   frame to a window no scaling is done.

2. PCI to PCI data transfer. fxtv aims the Bt848 to a given area
   in the display frame buffer to where to blast the video stream
   to -- there is no faster way of displaying video from a 
   PCI device .

3. In PCI to PCI mode the Bt848 does the scaling

I own a Matrox Millenium and you shouldn't have any problems with 
watching 640x480 32bits at 30fps irrespective of the resolution that
you are running --- I guess the real limit is the amount of memory
that you may have on your adapter however in your case thats not
a problem. 

	Enjoy,
