maybe an idea for an external, 6 inputs, creating that stream and 
sending it to the card to let it disassemble and send it to the 6 
outputs. 2 Cons: - might involve some patents of dolby labs and so costs 
a fee
- that stream typical is lossy encoded as AC3 so the musical data is 
changed which is to avoid. I don't know if there is a layer above or 
below to speak direct to the card but I guess this stream is sent to a 
decoder chip and than direct to the dacs.

An xbox is a cool idea although I wanted to give as few as possible 
money to M$. But I will think about it...
