Hi. I have a Toyota prius 2nd gen S Touring. I have TV and HDD navigation system. I want to know, is it possible add an extra DVD player and use the MFD display for watching. Please help me.
Yes it's possible. There are connections at the rear of the headunit (at least on the US-spec cars) that allowed owners to plug in an external accessory such as an iPod connector or a DVD player. Here's a link to a DIY (Do it yourself) with instructions in the PDF. You can see what parts you need and how it looks like behind the radio.
