LVW-5045 Projector & surround sound?

Hello everone, good forum by the way.

I have purchaced the LVW-5045 and have seen others use a projector via component, my current dvd set up is with a 5.1 surround speakers and Benq projector, can anyone advise on the surround sound set up for the Liteon LVW-5045 ?

If no surround connection is possible, do I have to listen to the soundtrack via the TV ?

Thanks in advance.
