Finaly upgraded to a system with dolby digital, i had a cheap one b4 with 5 speakers and a sub but just a simple audio jack plug-in, i just got a samsung for 270 at best buy, its got the 5 speakers and a sub plus the dolby digital, i didn't know you need the digital cable at first, got it now and it sounds freakin awsome. Especially on socom! plus i bought the the tritton 720 headset for the ps3 and it has dolby on it also, sounds sooo cool
