Okay. Now that I am completely confused about the various HD formats, let me try some specific questions. I have an HD satellite tuner that can output in 720p or 1080i. I also have a DVD player that can output in 480p. If I output a 1080i signal from my satellite tuner, will the 1080p TVs on the market display this in 1080i or will they convert it to 1080p? If I output a 720p signal from my satellite tuner, will it display in 720p or be converted to 1080p? If I output a 480p signal from my DVD, will it be displayed in 480p or be converted to 1080p? Finally, if I have one of the 1080p TVs currently on the market that appear to accept 1080i and convert it to 1080p, what will these TVs do with a 1080p input signal if devices start outputing in that format? Thanks for any help I can get.
