Carol, the guys have already told you the in and outs of digital vs. analog tv. I myself don’t do the techie thing, hubby is the supervisory inspector of cable installation for the major cable company in the state of La.
Simply… you don’t need a new tv. A converter box as mentioned can be had at a place like radio shack. If you have cable service they supply the converter box, their techs install it and can explain to you how it works with your DVD player. Sometimes having someone in the room to show you hands on HELPS!!! Besides some of the techs are cute, cute!
