most 4:3 HDTV's have around 810i resolution instead of 1080i on 16:9 HDTV'sFrom what I've read in various threads, including this thread about HDTV, that's not correct. Current consumer-grade TVs, 4:3 and 16:9 alike, don't provide the full 1080i resolution. You'd expect 4:3 and 16:9 sets to have similar capabilities since they use the same general hardware and designs.
