Our 2010 PC came with a Samsung DVD with surrond sound built in. I wanted a Blue ray DVD player, but Stuart could only find a Sony with the controls on the front with an up charge of $380. I did not want it that bad. The player needs to have the surrond sound built in to power the five speakers already in the rig and the controls need to be on the front in case you misplace the remote. Only a couple of player meet these requirements.
I would try to fix your current unit. You can always use my grandmothers way, give a good wack.
