I have a new digital HD TV. On the back it has connections for both analog antenna and digital feed. Our local antenna is converting to digital. When I hook up the antenna to the digital input I get the newly converted ditital channels great over my old UHF/VHF antenna. I also have direct TV via satellite and a video cassett recorder & DVD player that are still hooked up to the old antenna via channels 3 and 4. Will I need to make major changes when everything converts to digital only?
