Play back Can the D1 play dvds, So much conflicting info. If it can how?

Hello I have the D1 and it can not play DVD's in the DVD Rom slot. It is only for use with the DVD Navigation Discs. To watch DVD's on the AVIC-D1 you need to get the Pioneer DVD Player or DVD Changer and connect it through the IP Bus and AV Bus to control it from the head unit. The other way to watch DVD's on the D1 is to buy any automotive DVD Player, for example Boss, Lanzar, etc. or use a PS2, PS3, or any other Video Game System that plays DVD's and connect it through the RCA AV Video and Audio inputs. I believe that the AVIC-D3 has the ability to play DVD's from the unit. It can also can play DVIX DVD's. Hope this helps.
