Home Cinema (Samsung HT-C450) will it work?

Hi!

I have WD TV Live and I was thinkinh of buying Samsung GT-C450 home cinema, but I’m a little bit confused. This home cinema has a DVD player. Now, I’m assuming that I can use the HDMI output of the WDTV Live for the TV and the optical audio output of the WDTV Live for the Samsung home cinema, correct? Does this mean that I just need to have the DVD player switched on in order to pass the surround sound to its speakers?

Thanks, but this isn’t what was I looking for, because I don’t want to connect the home cinema to the tv. I want to know if I can use the home cinema only for the surround sound.
