I have bought myself a component cable to connect my Iphone 4S to my TV. The main reason for this was so I can use my Virgin TV Anywhere app to watch programmes on a TV when not at home. Connection is fine and I have played a You Tube video through the connection but when I try the VM Anywhere app I only get sound and no picture? The message on the picture says 'video mirroring is not allowed'. Is this an issue with the connection, the phone or VM??
