I have a TV that has all three - FireWire, HDMI and CableCARD. With FireWire
the convenience is that the TV controls the cable box however you don't have
any of the on-screen displays, including the guide. The CableCARD gets the
guide as well but the most useful by far is the HDMI input from the cable
box. And since Comcast makes you pay the same price for either a CableCARD
or cable box having a cable box makes much more sense as you get the
on-demand, guide, etc.
