IfoEdit

Editing the content of a DVD video is an easy task, provided you have the right tools to carry out the job. IfoEdit is an application that aims to help you on that matter, providing a set of tools for handling VOB files with ease.
The main purpose of IfoEdit is to assist you in merging, cutting, editing, creating IFO backups, extracting DVD parts or even authoring a new DVD. Its interface is rather blunt, but well-organized, providing fast access to all the tools and features.
The application adopts a simple approach to opening the VOB files typically stored at the root of a DVD and displaying their content. Checking the DVD-R size, verifying the m2v file and the GOP structure, restoring the cell in the VOB files or saving the cell times locally are just some of the variety of tasks that you can perform using IfoEdit.
In addition to this, you can use it to extract and remove audio sections and subtitle streams that are no longer needed, strip the VOB IDs or split the DVD into two smaller DVD-Rs.
The program comes with a tool that can help you create a new IFO file to accompany the VOB one. IFO files are the ones that provide all the information required by DVD players, which enables users to play and browse the DVD content (such as chapter starting points, the location of subtitles and audio streams, menu structure and so on). Thus, a corrupted IFO file results in a non-functional DVD, unless the BUP backup file does not take its place.
IfoEdit can also be used for merging menu tables, bypassing the APS protection of your DVD (which allows you to copy its content without restrictions) or changing the subtitle colors, to make them more visible to the human eye. Furthermore, it includes options for extracting VTS sectors or generating disc images.
The DVD authoring tool that IfoEdit comes with enables you to easily create a DVD by specifying the digital audio, video and graphic content and the navigation configuration that are then multiplexed together to generate the VOB file.
Overall, IfoEdit is an easy to use application for those who are frequently dealing with these types of files, allowing them to modify the content of a DVD and getting rid of unwanted elements without altering its general structure. Therefore, it is advisable to use it only if you are sure of what you are doing, in order to avoid data corruption, which could make the DVD non-functional.
