When encoding from DVD, it is often desirable to select a chapter or

range of chapters to encode.
|

You can use the <option>-chapter</option> option for this purpose.
|

For example, <option>-chapter</option> <replaceable>1-4</replaceable>
|

will only encode chapters 1 through 4 from the DVD.
|

This is especially useful if you will be making a 1400 MB encode
|

targetted for two CDs, since you can ensure the split occurs exactly
|

at a chapter boundary rather than in the middle of a scene.
