Well, I guess you could modulate them on unused channels for distribution to
TV's - then install a TV tuner card on the PC - hell I'm watching Family Guy
right now in a window.   But that is not going to turn the PC into a DVR (not
sure if that's what you wanted).  It would just allow for monitoring the cams
on the PC and record 1 at a time.

You can split the signal and send un modulated feeds to a PC capture card for a
home built DVR.   And then modulate the 2 from the split and inject them into
the cable (get's more complicated if she has SAT).

OR..  Get a capture card and use the Monitor output to modulate for injection
on the CATV/SAT.

OR.. http://www.napcosecurity.com/video.html

Or maybe wireless video Tx-Rx for the TV's set on the AUX inputs if you don't
want to fuck with channel modulation/injection.

I'll think about it some more... gotta run.
