Add CAMERA to your beo4:
- press standby + list together (display shows ADD)
- GO
- press list or arrows up/down till you see CAMERA
- GO
Now press list till you see CAMERA and GO
If this works: There is also AV4. It has 2 cinch-connectors you can use. Check the drawing on the backpanel. Just name in the connection menu for example PC and add PC in your beo4. Like I said in the explanation above.
