» Working With DVDs and VOB Files:
VOB files are the files on a DVD that contain the actual video, audio, subtitles, and menus for the DVD. Video and Audio on a VOB file are compressed using MPEG-2.
With Digital Media Converter, you can convert VOB files from a DVD into any of the video and audio formats that Digital Media Converter supports. One very useful technique is to convert VOB into WMV files, which can be played on a Portable Media Center device. VOBs can also be converted to work on an Apple iPod or Sony PlayStation Portable (PSP).

Types of VOB files:
• VOB with chapters: DVD authors often divide the content into chapters. The chapters can be individual episodes of a TV show, scenes in a movie, cut scenes, or trailers. By dividing the DVD into chapters, it becomes possible to create the navigation menus and let the viewer jump directly to a desired part of the DVD.
VOB Files can contain multiple chapters. These chapters can be seen as chapter points in the VOB file using Digital Media Converter. The software can either extract the chapters (so that each becomes a separate file) or convert the entire VOB file (all the chapters) into a single new file.
• VOB without chapters: These VOB files are undivided - they contain only one video stream. It’s easy to recognize a chapterless VOB file while you use Digital Media Converter. If the file contains chapters, the software alerts you.
Scanning VOB files:
• Scanning for chapters: When you add VOB files to the list of files for conversion, Digital Media Converter scans the file for chapters. If the file contains chapters, a dialog explains:
The window above tells you more than just, "The file has chapters". Under More Information, the software informs you that only the duration of the first chapter will be shown in Digital Media Converter's listing, and that when the file is converted, all its chapters will be combined into a single file.
• Scanning for Encryption: Some commercial DVDs are encrypted and cannot be manipulated. Along with the scan for chapters, a file is also scanned to see if it is encrypted. If Digital Media Converter detects an encrypted file, it warns you. The software does not convert encrypted files.
VOB file Conversion with Digital Media Converter:
You can separate the chapters of a VOB file using the Extract VOB Chapters option under the Tools menu. You can see the individual chapters and choose to include or exclude chapters from extraction by checking or unchecking them. If you do not use Extract VOB Chapters option all the chapters will be converted and you will not be able to view individual chapters in the listing.
Extract VOB Chapters option will be active only when you add a VOB file with chapters. Once you extract the chapters you can choose to split or delete them.
Split VOB Files and Chapters:
You can split a DVD into several sections by splitting the VOB file or a chapter present in it, using Digital Media Converter. For instance, you can use the Split File Function to convert only a trailer of a movie or a particular scene.
In the list of files (or chapters), highlight the file to split. Either use the Tools menu or select the file, right-click and then select Split File. The following window appears:
Split Functionality:
• Split the Source File manually: You can split a file manually using the preview of the file. As you see the movie in the preview, you can easily decide where you need to split it. Drag the slider to the point where you want Digital Media Converter to begin including video, and select Mark In. Now drag the slider to the end of the selection you want included and click Mark Out. You can use the preview to easily identify where to start and end the conversion. When you click Add, the section you have marked is added to the conversion list. You can mark and add another section or click OK.
• Split the Source File Automatically: There are three ways to split files automatically. If you choose to Limit each clip to, you can specify the duration and Digital Media Converter automatically splits the movie after that time- for instance, every 30 minutes. If you select Split into, you tell Digital Media Converter to break the file into a certain number of equal-length pieces. Finally, Auto fit to tells the program to split the movie into pieces small enough to fit a particular kind of disk, either single-layer DVD, double-layer DVD or VCD.
You can manage DVD content using Digital Media Converter. A DVD may contain a VOB file with chapters. You can combine these chapters to make a single file, or extract selected chapters to individual files. Different VOB files don’t get combined; it’s the chapters within a VOB file that are merged. Digital Media Converter enables you to split files in a DVD, combine chapters into one file and convert DVD video and audio to many different audio and video formats.
