I have become confused by the different types of DVI cables. What are the differences? For example, the Panasonic PT-L500U takes DVI-D in, the Sanyo PLV Z2 takes DVI-I in and the Samsung "HD" DVD player has a DVI outpu (don't know which type). So lets say the Samsung is DVI-I. Would that mean that you could not connect the Samsung DVD player to the Panasonic Projector? Does the I/D mean anything, or are the cables used for them identical, and it is just the output that is different, say Interlaced and digital? I am totally lost and would appreciate help.
