There is something wrong when converting VOB file, what can I do?

As for the case, please check whether the .VOB file is just a common video or a video from a DVD Folder/Disc.

A: If the video comes from DVD.

Actualy, this program only supports converting common videos, but VOB files from DVD must be depended on IFO file.

IFO is a DVD information file that stores information about Chapters, Subtitles and Audio Tracks. An IFO file is one of three types of files that are used on DVDs. It contains important navigational information, such as where a video chapter begins, and where audio and subtitle streams exist within the movie (VOB) file. IFO files are not encrypted.

So please download DVD Ripper program from our website and then add the corresponding IFO file into the DVD Ripper program. If the VOB file name is VTS_01_1.VOB, you just need to add the VTS_01_1.IFO into DVD Ripper program.

Please check if it plays well on your computer and then send us the file for further analysis.
