Whats the diffrence between 1080i and 1080p? Does the price diffrence justify buying a HDTV that can do 1080p? Upgrading from a 36'crt tv to a 60 + hdtv.

• Very nice answer.
  What about HD-DVD or BluRay?

• HD-DVD and BluRay are both storage formats, not screen formats. They will store whatever people choose to write on them. 1080p requires twice the data capacity of 720p or 1080i, but I imagine both of them would be capable of storing it. You could only store half as much material, of course. But until film-makers make material in those formats, nobody will be writing them to disc, however big and fast it is. Initially, people will be making them for the broadcast formats. Remember that traditional film is only 24 fps, so there is no point in going to 60fps for old films. You would have to shoot at 1090p to make it worth while - whic people are not yet doing.

• Thanks. I'm glad you answered that according to my general question. The question was in reference to "I would not thin k it worth going to 1080p: it isn't going to be broadcast for a long time yet." The question should have been: What format will HD-DVD and BluRay be in? But you answered that :)
