 ===== Ripping the .vob from the DVD =====
+A DVD can contain several **titles** and you should identify which one you want to rip; generally it is the longer one or the one with most chapters. We check the DVD content using the **lsdvd** tool:
+<code>
+lsdvd /dev/sr0
+Disc Title: DVD_TITLE
+Title: 01, Length: 01:02:36.480 Chapters: 03, Cells: 03, Audio streams: 02, Subpictures: 04
+Title: 02, Length: 00:00:12.800 Chapters: 01, Cells: 01, Audio streams: 02, Subpictures: 04

+Title: 06, Length: 00:20:24.720 Chapters: 01, Cells: 01, Audio streams: 02, Subpictures: 04
+Longest track: 01
+</code>
+The longest title is the **#1**, so we will extract it using **vobcopy**:

 The .IFO file is required to get the correct palette, width and hight, but it is not mandatory.
