Joey inherited an LCD TV and he needs an adapter to plug in from his old coax cable box. Leo says that coax is an analog connector designed largely for over the air antennas, rather than digital, which is what HDMI or DVI is. Leo says it's going to cost Joey more to get a Coax to DVI converter than it would just to get a new cable box. Then he can get an inexpensive HDMI to DVI adapter. He'll also need a separate sound cable. Since Joey also has component, another option is to go from Component to DVI. That's an inexpensive option as well. But then he could end up with sync issues.
