[FFmpeg-user] Note to document maintainer

As a newbie I tried the following example:

The following example shows how to use ffmpeg for creating
a sequence of files ‘img-001.jpeg’, ‘img-002.jpeg’, ...,
taking one image every second from the input video:

   ffmpeg -i in.avi -vsync 1 -r 1 -f image2 'img-%03d.jpeg'

So what's the change/addition to create an image every two seconds?
Every three seconds?  The needed switch may be buried in
the overall documentation. Having it in the "section 9.3 image 2"
would save newbie's a lot of searching.

Also, the single quotes above fail under Windows XP and the correct
command is: ffmpeg -i in.avi -vsync 1 -r 1 -f image2 img-%03d.jpeg
