There are three common situations that you want to convert DVD to VOB format: transcode DVD movie to a single VOB file; convert the BUP, IFO, VOB files in the Video_TS folder to one VOB file; copy DVD to Video_TS folder which contains many VOB files.
For the mentioned or other different purposes, lots of you need to rip DVD to VOB file format. As we known, VOB (Vidoe Object) is the format container of DVD video and it is used to store data of MPEG-video, audio tracks, subtitles, DVD menu, etc. Remember, just copy and paste the VOB files from the DVD disc is not the right solution and it won’t be helpful at all. Except for homemade DVDs, most of the DVD discs that you bought or rented are copy protected DVDs and the CSS (Content Scramble System) will disorganize the correct DVD playing order. Only with the advanced DVD decrypting technology, you can play and copy the DVD movies normally. In this case, to rip VOB from DVD, you need to take advantage of the third party tool.
