    Does this happen with all DVD's? as if it does, it would suggest possible instability in the actual DVD playing circuitry and something you cannot really do anything about.

    Also has this just happened?, as a subwoofer is one of the worst things to show up design deficiences like disc drive motor electrical noise. (or possibly through a defective filter component)

    Pull the input connection out of the back. If the hum is there without any input, it's either a fault or a design fault. Unfortunately subwoofers are tuned to the very frequencies that a bad power supply will leak out (50 and 100 Hz). I used to have a Pioneer sub that hummed like that - I cured it by replacement.
