When the sub is on, what do you have the volume on the sub set to, and what is the dB level on the receiver for the sub? I can't believe that would matter, but just wondering. Also, how close are the DVD players to the sub?

You've got a weird one here Tarun. Why do you think it is no longer the projector?
