yes some games did HD on xbox. HD is just the rez not the graphical power. all you needed was component cables and an HDtv.

If im not mistaken, it's not just a resolution. It's a specific wide-screen resolution.... "HD format" = 1280x720 and 1920x1080 to be exact.

Actually the whole 720 and 1080 resolutions are a fake resolution standard. The resolutions were created by TV manufacturers because they were to damn lazy and cheap to add the extra horizontal lines that would have brought them to the real HD resolutions of 768p and 1200p. They wanted a wider screen too because people think cinemas have wider screens when in reality they are all full screen resolution movies in theaters but more in the scale of the 4k+ resolutions.

Most movies are filmed for even wider screen than current TV:s are. Biggest movies are filmed on 70mm film which has 2.35:1 aspect ratio (around 21:9 ratio). During sixties there were a lot of movies with even 2.7:1 aspect ratio. Majority of the movies are filmed on 35mm film though which has 1.78:1 (around 17:9). Yes, when these movies are shown full screen on TV, you only see part of the movie.

Actually, 35mm can accomodate both 2.35:1(Scope) and 1:85:1(Flat) depending on which lens type is in use.  I managed a theatre while in college and built movies(spliced all the reels together onto a platter system, usually around 6-7 reels per movie).  Even without the information on the header and footers of the reels, you could tell wether a film was flat or scope by looking at each frame to see if it looked stretched(Scope) or had black bars(Flat).  With flat films, not all of the 35MM frame is used.  With scope more picture information can be stored, but special lenses are needed to project it correctly.  Theatres have masking so that they can adjust the size of the screen to the appropriate aspect ratio.
