Not necessarily. Among my local stations, PBS is in 1080i, 16:9, Fox is in 720p, 4:3, NBC is 1080i, 16:9, ABC is 720p, 4:3, CBS is 1080i, 16:9, CNNHD is 1080i, 16:9, but the actual picture area is 4:3. Other HD channels have the same variations; some are 4:3 and some are 16:9. I guess they are assuming that there are still more CRT sets out there than wide LCD sets. Oh, there are some HD sources in 720p that are 16:9 also.

Just because the channel is an HD channel doesn't mean the program was shot in high definition. What you're seeing is upscaled from 4:3 480i. Kind of like you playing a pan & scan DVD on your HD set. Your TV is displaying 1080 or 720, but the original source is still 4:3 480i.
Some stations are now thinking they're slick and zooming the SD camera signal so it fills out the sides and cuts off the top and bottom. Looks like ass to me, but a lot of people are hard pressed to tell the difference.
