but by default, in America, the video display unit in my house is referred to as a TV. Even though the signals received are from either a dvd player or a vcr.
If I told people I had no TV, when they walked into my house most would point to the vdu and say, "Well, if you don't have TV, what's that?!"
(btw, what is the better term for video display unit. Monitor refers to computers or speakers. Video player refers to the dvd or other media player. Entertainment system refers typically to the furniture, and not your HT (which I've always thought odd). I can't really say screen, cause I don't have a projector (same with video projector). I supose it should be television set, but that's a bit antiquated, I think)
