I am contemplating on buying the X-fi I/O Drive upgrade kit. I currently have the digital i/o module that I use to connect to my crappy Sony str dg510 A/V Receiver for when I want to watch movies on my TV and when I game I use my JVC HA-RX700's. When using the digital i/o module to my receiver(using coaxial), It always comes in as 2.0 no matter the movie or show I have in my dvd drive or hdd. I put the x-fi settings to 5.1 but usually still comes in at 2.0 to the receiver. So I was possibly thinking that buying the i/o drive upgrade kit, I have a dedicated spot for my jvc's and possibly using the kit to connect to my a/v reciever. Is it worth it?
