Ouch!
My life is contract negotiation... I'm a VP/IT & CIO and what I've found is that people are willing to do something for you if you can do something for them. I have no idea if it will work for B&M - or if you are willing to try it - but do they have any other similar or better DVD player (I have a Denon and a Cambridge and can recommend both) that you would be willing to trade to for a nominal sum? If you can put something into it for them, even $50, then they may be willing to make it work for you.
Or not. But it's one of those things that may be worth a try if you are willing.
