Thank you for responding to me directly - as I was unsure of the

You're correct about needing to buy a cable / bracket for this card.
I would certainly get you a card, cable & bracket to you if you have
an interest in further development!

I hadn't even thought of this - at all -. Thanks for the insight.

This is absolutely true as well - Does anyone on the list know if
there are any PCIe w/ component in cards working in linux?

Absolutely! It seems like the best option for us right now is to grab
a few Hauppauge HD PVRs. Although, should we worry about usb being a
limiting factor (and I've read a lot about needing to power cycle the
units every so often - due to freezing and not correctly stopping
recording of a show)? I know the bitrate can get as high as 13.5mb/s
for each device, and we're looking to have 4 channels of recording /
view available to us at once (large family).
Thank you very much - again :)
