I'm not sure why it would not work taking the line level out from your DVD into the preamps and then to amps. You might try it with, say, fronts L and R, and see what happens. With two preamps you could control the volume and balance of each channel. You would need another amp for the center, but a $20 gainclone (T path amp)from Target or Parts Express would work well.Curious - what bramd and model of DVD player do you have?......Colin
