I was thinking of getting the Vizio VHT510 system for my Panasonic TC-P50ST30. The main question I had on this system is this: The Vizio only has an optical in. I would be having everything going through the Panasonic then. If I was to play a Blu-Ray from my PS3, would the Panasonic be able to decode the right sound format, like Dolby DTS? Or would I have to get a splitter box and have to switch the source going into the Vizio?
