When connecting a DVD/ Blu-Ray player to your VR-3EX it's important to know that those type of devices carry a HDCP signal embedded on the output of the HDMI port. HDCP is copyright-protection technology that prevents unlawful copying of content by encoding the path when sending digital signals from a video playback device to a display monitor or other display equipment.
When inputting signals to which HDCP is applied, follow the procedure shown below to change the settings:
Press the [MENU] button
Use the > button to get to Setup
Press [SETUP] on touch screen
Press [HDCP] on the touch screen menu
Use the VALUE knob to set to "ON"
Once you have successfully enabled HDCP you will notice that the HDCP indicator light will be turned on. It's next to the "IN/OUT SETUP" and "MENU" Buttons to the left.
If you see the light blinking/ flashing that means no HDCP-compatible device is connected to the HDMI output connector. Or a device that does not support HDCP is connected.
What you want is the light to be on solid and that indicates an HDCP-compatible device is connected to the HDMI output connector.
