Basically, you cannot do that with a DVD disc on your DVD drive. Even if your computer allows you to rip multiple DVDs at once, it is probably for your computer to crash due to overwork. That’s the reason for finding a great DVD ripper software to help you out. With good software, you could rip DVD fast and save a lot of time.
That being said, if the source is an ISO file or a DVD folder, you can do that if your computer has a strong CPU processor. For example, DVDFab DVD Ripper could make the ripping process 2X Faster with the VideoToolbox Hardware Acceleration function. That way you might try batch ripping with this strong DVD ripping tool.
