From all that I have heard and seen, Jewelsy, take that DVD vs. TV/Video difference and at least double it, or even triple it. HDTV really is that good....if you have all the right connections hooked up AND are able to receive an HD signal from somewhere. I think LoneStar said it best when he told me "Its like looking through a window".
BTW, LSS....satellite companies DO offer HDTV, but since it takes up so much bandwidth, you have to get a different dish that is able to bring in signal from a satellite with a different orbit/sky location, and a different receiver box. DirecTv and TiVo are about to debut a receiver/unit that will record 10-20 hours of HD programming, or up to 200 for regular programming. Yeah, the bandwidth is quite a hog!
