I don't know if this is the right place to post this question. I am a HDTV newbie. While I have had a television capable of High Def for sometime now, I just decided to get a HD signal via a cable card. Here are my video observations so far: The nature shows and travelogues are mind-blowingly clear, and it is better than real life. NCIS was shown in HiDef last night, and I was less than impressed. Do all network shows look this mediocre in HD? What defines HD? Do shows have to be shot with HD cameras to look incredible? Most of my TV on DVD looked better in standard def than this episode of NCIS in HD. If this is a reflection of what TV on Blu-Ray will look like, I will not be rushing to buy one anytime soon. Any comments on this issue would be appreciated. I'm trying to learn.
