I see, tnx.Do you have any other suggestions for HTIB with working build-in decoders using Optical?

Hi, today i decide to buy home theater system to finally play my games and movies with 5.1 DTS sound on my PS3.I was thinking to buy this one

Sony DAV-DZ260

because it's not very expensive and have good sound, but i'm not sure that the system provide 5.1 surround whit optical from PS3, because on the manual there is nothing about build-in DTS, DOLBY DIGITAL or DOLBY PLII decoders.

And my question is if i buy this Sony HTIB does i have true 5.1 dolby from my PS3 and if i'm not, what system i need to buy to have the proper 5.1 with my console in the games.

Thanks in advance for the answers and suggestions.
