Ripping a DVD
There are many DVD ripper software out there, and many people just use it to decrypt a DVD and copy the vob files as they are on DVD minus the encryption. In that sense most do a good job. But we want to separate the vob files by what is called a VOB-ID. This solves a few problem:
- Subtitles done by VobSub will be in sync
- Audio created by DVD2AVI will be in sync
- Solves Alternate Angle/Seamless Branching
vStrip (homepage) is the most flexible DVD ripper that's currently out, and with the latest vStrip_CSS
GUI it's as simple as any other DVD rippers. You will need the version with CSS.
Before using vStrip, your DVD drive needs to be unlocked. You can do this easily by starting up a DVD ripper software such as SmartRipper (see download section at doom9.net) and just leave it open.
Start up vStrip GUI, and click Add... button. Select the vob files to be ripped. Which ones to rip should be obvious by file size. Generally choose the biggest VTS_XX set like this:
Note the lack of 0.vob file. 0 files are not normal movie file, but contains menu data. So do not add them.
The example is from actual DVD called Judge from Central Park Media, which contains alternate angle.
Go to Output tab. Click on Output Name and select the directory and filename on your harddrive to rip the vobs to like so:
Under the Split File Size, choose 1024 MB and check By VOB-ID. This is critical.
Click Run button.
After this finishes, you'll end up with files like these:
Rename VTS_03_V02C__.vob to VTS_03_V02C___0.vob. This'll make it easier to load into DVD2AVI since it'll autoload the sequencially numbered files.
