Why don't all DVDs have a choice of FS/WS?

Now, what do these four bytes do? They're 2 16-bit integers. one is "left side crop" and the other is "right side crop". They give a width, in pixels, that each frame should be cropped for display in widescreen mode.

Now, when someone goes to play the movie in widescreen, these numbers are ignored and black bars are displayed at the top and bottom of the screen.
When someone chooses to play the movie in full screen, the picture is enlarged so that no black bars are visible, and these numbers are used to select what part of the original picture is displayed on the screen.

I should be consulted before the next big video media format is finalized

actually all players have that capability, but for some reason the studios never released a compatible disc.

plus the fact that the action takes place on the side of the screen, sometimes....

yep. you got to admit that the technology, had it worked correctly would have been a great solution to those who like Pan and Scam movie and those who prefer to watch the movie as the director intended it to be shown.

They dont have widescreen and full screen because they would take up too much room, and they would have to lower the quality to an unacceptable level. Also, people who watch full screen movies are retarded.
