Sorry if this doesn't make much sense, my friend has a HD Panasonic TV linked to a Panasonic DVD player which has a surround sound system into the back of the DVD player. She now wishes to buy a BR player but the surround sound doesn't seem to be compatible as the BR will probbably have an optical in for the sound (I think) is there anyway to link the two so she only needs to replace add the BR and not replace the surround sound as well?
