I hope the previous suggestion helped you. I would just say that a volume level of -30 does not seem particularly loud. I live in a ground floor flat, so obviously have to be neighbourly, but my maximum level is -18. Admittedly, that is pretty loud though. My thought was whether you have some settings active on your dvd player which may boost the LFE channel. Sometimes there are settings on amps for bass boost too, which are often buried in the settings.
