I have a Rocketfish TV out cable (with the red, white and yellow RCA connectors, NOT HDMI) that I used with my iPad 1 to watch movies on our TV. Now I have the 4, and I added the 30 pin to lightening adaptor, and it doesn't work. I get audio over the TV but no video. I tried using the TV Out app, which doesn't seem to do anything. Any suggestions for making this work? I have no need for the adaptor otherwise. Thanks!
