DVDVob2Mpg is a simple, free, straightforward and very fast VOB (or VRO) file to MPG converter.
Contrary to popular belief, VOB and VRO files are not the same as MPG files. VOB and VRO files contain the MPEG, but also various other data, and headers may be incomplete or wrong etc. Because of that, VOB and VRO files typically don’t play well using media Players (for instance Windows Media Player). Some DVD Video Playback software is able to get past that, but not always, especially when the relevant IFO files are not available.
Typical problems are: timing issues, not being able to show the progress properly, no way to skip forward, crashes, missing audio, audio off sync, only showing the first 5 seconds of the video etc.
DVD Video authoring applications and Video Editing software suffer from the same problem. They may accept VOB/VRO files as input video, but they often fail or even worse, crash on faulty headers, timing data etc.
The same goes for VOB or VRO files that were recovered from DVD, for instance with IsoBuster. They may miss sectors, because parts of the DVD were unreadable, or the DVD file-system was bad so that IsoBuster needed to resort to recovery based on File Signatures, which may mean more overhead data in the data stream etc.
DVDVob2Mpg fixes the MPEG stream and converts your VOB/VRO files to MPG files with ease. DVDVob2Mpg is very fast and causes no loss of quality ! It does not re-encode the video and audio like so many other applications do. Instead it re-multiplexes the existing video and audio while it fixes the MPEG program stream and headers, it calculates and applies correct timing, throws away bad video frames and nonsense data. At the end everything is puzzled back together to come to a very clean MPG file, per the MPEG standard. MPG files created with DVDVob2Mpg will play beautifully using Windows media player, and they will import with ease in all Video DVD authoring applications or Video Editing software.
If you wish to edit your video, change size, apply filters, remove scenes etc. you will need Video Editing software. But before you do, first convert your VOB file with free DVDVob2Mpg to a very clean MPG file. It will save you lots of frustration.
