I found a receiver at Best Buy open box for $225 is the Sony STR-DG800. Can someone look at this and let me know if it's worth the money? I've been researching and researching and it seems to look okay, but I'm not sure if it will make things better for me.

I want the audio from my PS3 when I play Blue Ray discs to sound better, it does the following:

DTS 96/24, DTS Neo:6, Dolby Digital, Dolby Pro Logic, DTS-ES Matrix 6.1, Dolby Pro Logic II, DTS-ES Discrete 6.1, Dolby Pro Logic IIx, Dolby Digital Surround EX

Are there other formats for BD that I need to decode?
