I think if you can alter the output from DSD to PCM on your dvd player it will send the PCM data via coax to the coax input on the Bryston? I don't dabble with these things so I am probably wrong.
Also if your dvd player will output the dsd stream via HDMI (like the Sony 5400ES does and probably others do as well) you can get one of these:

and I believe this unit takes the dsd stream and converts it to PCM for transfer out via coax to any DAC - again I have no prior experience with these units so I cannot say for sure.
There was a similar thread @ AVS Forums and possible over at Audiocircle where this type of product was discussed and if you can't find out more info here try there...
Good luck!
