TrueDVD is a movie player app developed by Hitachi-LG Data Storage Inc. for Android devices. It is designed to play DVD videos on smartphones and tablets that support Androidor later with USB OTG support. The app also supports portable DVD writers including GPM2, KP95+, KP96, KP99, GP96, GP75Y, and GP78Y.

The app comes with a guide for connecting it to a portable DVD writer, which involves connecting the supported writer and smart device according to the user's manual. If the DVD video is used while DISC LINK Platinum is running, TrueDVD is automatically executed. If TrueDVD is not installed, the user is automatically taken to the installation page. The app can be used even if TrueDVD is run directly. To choose TrueDVD for the USB device on the smart device, click 'OK' on the pop-up window. Users should execute it by pushing 'JUST ONCE' after selecting TrueDVD; otherwise, they cannot execute DiscLink App in the next ODD connection.

Overall, TrueDVD is a handy app for playing DVD videos on Android devices with USB OTG support and portable DVD writers. However, the app might have some compatibility issues depending on the device.
