VOBs are subject to the DVD specifications, so the episodes/titles (PGCs) on the DVD are split into different VOBs, which means one episode will be split to the next VOB, or rather, various episodes are contained within the VOBs and may extend into different VOBS.
Then if you want to get complete episodes that extends from one VOB to another one into individual files, how do you do it?
The simplest way is to get the DVD ripped in separate episodes when ripping the DVD to the hard drive, using DVD Decrypter in IFO mode or DVD Shrink in Re-author mode. For specific operation, please refer to the articles relevant to this topic: How to Convert TV Show DVD into One AVI File for Free and Convert Each Episode of TV Show DVD to Individual AVI File Using Freeware. But if the DVD is already on your hard drive, there are two free tools to help you make a complete episode from different VOBs.
VOB2MPG
VOB2MPG goes through a whole VIDEO_TS folder and joins up various vobsets to produce MPGs for different titles without reconverting the video and audio. So it will split your VOBs into individual complete episodes/titles.
PGCDemux
Open the VOBs or the IFOs in PGCDemux and check “Create a PGC VOB”, and then it will output the individual episodes in the form of PGC VOB files.
Don’t forget to try our DVD Ripper which allows you to load the whole DVD folder or open DVD disk to get individual episodes and even individual chapters from one episode into whatever format.
