You should use HDMI interface between the TV and DVD player. Then use a reasonably priced IC from the DVD to preamp (HDMI carries both the audio & video signals). You will want to take advantage of your plasma TVs video capabilities by utilizing HDMI, even if it means purchasing a new DVD player (if your current player does not have an HDMI interface). Even the most modest-priced newer units have HDMI. Spend more on the HDMI cable than the IC's at the onset. You can upgrade the IC's later
