Ok, I kind of have a series of questions, as I pretty much know nothing when it comes to audio. I currently am using an Airport Express to stream music to my Pioneer VSX-D812 receiver. I also use the Vuze program to stream video through my xbox 360. My questions are as follows:

1. Is it possible to set up surround sound through Airtunes? If so, how would I go about doing that. What kind of cables would I need to connect from my Airport to my receiver?

2. If it isn't possible to do surround sound through airtunes, is there anyway to just make the same sound come out of 5 different speakers (2 front, center, and 2 in the back)?

3. Is there any way to stream my videos through Vuze in surround sound? If so, how is this possible.

Any help is appreciated...
