Although some try to connect an external DVD Drive to mobile or table for playing DVD, the process is quite cumbersome for most people and it has requirements on device model and other things, which would take a long time to figure it out. Besides, I would not recommend to directly copy files from DVD folder to Android for watching because many DVD movies are copy protected and the video files may be broken. Instead of finding a DVD player for android tablet and phone, you might as well use WonderFox DVD Ripper Pro to convert DVD to your compatible devices. This DVD ripper can remove any DVD copy protection, and convert DVD to almost all tablets and phones. It only takes three steps to rip a DVD.
Download the DVD ripper and see how to easily rip a DVD to Android.
