Just looking through the manual for the Pioneer PDP-434HDE. I see that the set has HDMI input but that the control box connects to the set using this input. The HDMI input is not replicated on the control box so effectively the set does not have HDMI. This is the same with the Hitachi 42PD5300. The box connects to the set with DVI but the DVI input is not replicated on the box. Why do the manufacturers advertise these sets with DVI/HDMI when in reality you can't use them as such. You would have to keep unplugging the cables in order to connect your DVI/HDMI kit. Ridiculous!
