Video mode will automatically be reset to default (auto) mode every time the DVD 50 is turned on. To confirm if the latest version of the software has already been downloaded in a DVD 50, follow these steps: 1) Connect the DVD 50 composite video output jack to the video input jack of a Television or monitor.
Page 41 Upgrade Disc, simply press the Open/Close Button and the drawer will open. Remove the disc, and then press the Power Button to close the drawer and return the DVD 50 to the Standby mode.
Page 42 Progressive Scan Image Modes The powerful video decoding and processing engine that is at the heart of the DVD 50 is able to provide a variety of modes to help compensate for the differences inherent in the way DVDs are recorded. In order to enable easy compatibility with the widest range of discs, the factory preset is an automatic mode that best determines the proper processing algorithms.
