This was a year ago; at the time there weren't any PCI-Express video 
capture cards.  Even now, I don't think there are any with good linux 
support.  (I'd love to be proven wrong; I am looking for a NTSC/ATSC 
tuner / video capture card I can put into a PCI-Express 1x slot...)

Well, it's actually a good deal if you use the other OS....  Instead of 
a plain NTSC tuner card, you get a NTSC/ATSC tuner card for the same 
price with better specs.  Except that there are no linux drivers for 
it... :-(
