From what I've read, true HDTV (either 720p or 1080i) is always widescreen. Shows that are 4:3 are just digital broadcasts in 480p. I could be wrong, but I just thought I would reply while you?re waiting for someone more knowledgeable to answer your question.
...Can anyone tell me if true HD programs are ever broadcast in a 4:3 aspect ratio? here in NYC with Time Warner, there "700 series" channels are all said to be HD, yet many of them (at various times) broadcast shows in stadard 4:3 aspect artios. these shows generally don't impress me as being HD but Time Warner keeps telling me that these channels are all HD. I don't buy it because sometimes these same stations broadcast in 16:9 and look really good. It seems to depend on program in question. Only Discovery (channel 706) and the PBS station (channel 713) seem to be in 16:9 HD all the time.
Can anyone tell me what's going on here?
Thanks guys!
