I have my computer with a nice sound card in one room but a 5.1 Home Theater system in another room. I'm wondering if when you network your music, such as from Windows Media to the Xbox does your sound card still process the sound and thus provide benefit or does the Xbox have its' own sound processing and just read the file directly. If this is the case, what is a good receiver that I can network my music to while retaining the benefits of my computer's sound card?
