How to merge several DVD .vob files into a single file
This post goes over how to merge a bunch of .vob files you into one large .vob file. I recently had to grab a few clips for movies at one of my clients. Now I don’t normally do this kind and since there wasn’t all that much help out there I figured I should do a post on this subject.
The reason why I needed to do this is when I was originally ripping a movie I deleted some of the .inf files and I no longer had access to the DVD. I normally use handbrake to convert the video files to DivX. If Handbrake can’t use the .inf files then you can’t merge the .vob files when creating a single DivX file.
So to work around this I needed something that could easily combine or merge the .vob files. One thing to note is your machine must use a file format that can read VERY large files. Most Windows PCs are now using NTFS as the file system. Things like external drives do not use this format yet. FAT32 can not support these large files. If you are having issues merging the files this could be the issue.
This whole post relies on a piece of software called: VOBMerge.
Once you have downloaded VOBMerge you should extract the files from the zip folder and run VOBMerge.
Click “Add File”.
A Window will open. Select the first .vob file that you would liked merged.
Do the last step for the remainder of the .vob files. I was in luck for this example. The movie I am working on was split up into two .vobs.
Click the “Merge” / DUMP button.
It will ask you where you want to save the new file that will merge the .vob files you selected in the previous steps.
Voila. That is all it takes.

Great thanks I ripped a DVD to hard drive but just kept the VIDEO VOBS, then Handbrake would not merge them into one MP4/AVC file. This seems to be merging them fine (and only taking couple of minutes so HandBrake can convert the movie into one file instead of multiple files.
