VOBUtils

VOBUtils is a lightweight tool that allows you to extract a stream from the TS_video directory of any DVD. You can use it to quickly retrieve a certain stream from the large VOB files used for storing the movie chapters.
The program uses the IFO file to identify the VOB streams and to display them in the main window of the program. It also displays the total number of streams and the size of the selected VOB file.
Before extracting a VOB you need to select the one that you want and the destination folder. Unfortunately, you cannot preview the images from the movie stream in order to identify a specific scene.
You can use the same application if you want to process all the VOB files specified in the IFO. Just use the Extract All button and specify the name of the output files. The name of the files is important since the app automatically overwrites the items that have the same name.
During the extraction you can follow the progress and stop the operation at any time. This comes in handy when you need a particular scene and you have selected the entire stream list for extraction.
The interface is simple and provides quick access to the main functions. You do not need to have previous experience in DVD authoring or decoding in order to extract a certain VOB. However, finding the one that you want to extract might be a little difficult.
If you want to convert only a part of a DVD movie, VOBUtils can help you by extracting the VOB from the DVD files.
