Portable DVD Player with iPhone 5 Dock

I have a RCA portable DVD player that has a docking station for the iPhone 4 and other models with the 30 pin connector. I have upgraded to the iPhone 5 with the 8 pin connector. I thought that the 30 pin to 8 pin converter cable would work or the HDMI connector cable but neither did. Does anyone know if there is a portable DVD player that has the docking station for the iPhone 5?
