Excellent, thank you Mike.  I'm using an older pvr150 in my shiny new 
PCI-Express motherboard and I'm looking forward to replacing it with this 
PCI-Express card.  If I can figure out how to split the cable I'll be able to 
run both tuners until I can remove the pvr150.

Are you saying that I will need firmware to view analog tv?

Judging by my schedule, I might not be able to test this out tonight after 
all.  Perhaps tomorrow night.  Are you saying that the 
http://linuxtv.org/hg/v4l-dvb stuff will not have any of your good stuff 
checked in?

Thanks for your help.  As you can see, I'm a newb here.  Advice on how to 
proceed is always welcome.
