 Video standards
 
-By default, webdvd generates PAL/SECAM video.  If you wish to produce
-NTSC DVDs you can override this by adding the option "--video-std ntsc"
-to the following commands.
+The encoding of analogue TV and video signals varies in many different
+ways between countries.  Happily there are only two parameters that
+matter for standard-definition digital video, and two different pairs
+of values.  You can choose between these with the --video-std option:

 Prior to Mozilla version 1.8, which I have not yet tested, Mozilla may
 signal that a page is completely loaded before any background images
