First question: On some DVDs, in the menu section, some will offer the choice between widescreen and fullscreen on the same side of the disk. How does it do this? Is the movie encoded twice, once for full and another for wide? This would not seem likely due to disk size constraints. Or is the movie encoded in a widescreen formate and the DVD is encoded to do its own pan and scan (or zoom) to get the fullscreen effect? Last question: Are movies shot in 2.35/2.40 formate ever converted down to 1.85? If so, wouldn't this be considered to be a type of pan and scan? Thanks for any input.
