If your Rotel DVD player is connected via component video, the output resolution must be set to either 480i (Interlaced) or 480p (Progressive). While the DVD player can output up to 1080i via component video, many DVDs contain a Macrovision copy protection "flag" that will disable the video output of the player at any resolution higher than 480p. If you wish to view DVDs at higher resolutions than 480p, an HDMI connection must be used.
