VOB2MPG is a tool that lets you easily convert VOB files from DVD folders into MPEGs.
The user interface is simplistic and easy to navigate through. There are two interface viewing modes - VOBSET mode (when you specify the DVD folder) and IFO mode (when you only specify the DVD's IFO file).
All you have to do is input the DVD source file, configure settings, set the output destination, and initiate the extraction process.
Once you have placed the respective VOB files in the queue, you can select which one of them you want to convert, view each chapter's start and end time, view the duration of a whole VOB, configure audio streams and preview the DVD movie.
In the Settings menu you can enable the program to remember window dimensions, auto play DVDs in preview, force AC3 audio, force aspect ratio, and eject source DVD tray when completed.
The program takes a few long seconds to load VOB files, but it manages to complete a task in short time (during which you can view the output log). Unfortunately, you cannot choose individual chapters to extract in the free version (only individual VOB files) and the program needs some codecs to work in most cases.
VOB2MPG uses a moderate amount of system memory, but other processes clearly run slower when the program is active (even Task Manager takes a long time to pop up). The program manages to keep a fair video quality and good sound quality.
Even so, it would had made more sense for the software to extract VOB files to AVI or another more user-friendly video format, rather than MPEG. Nevertheless, VOB2MPG is a great tool for converting VOB files to MPEG.
