Hello, I am working on a G4 Dual 1G with the memory maxed out. My question is how do I get surround sound in and out of the computer. I am trying to create surround sound for a DVD and I want to be able to hear it in true form when I am creating it and not in stero which seems to be the only way. Are there any cards, software, etc... to facilitate this or do I need to upgrade to a G5 (last option)? Apple's site seems to lack any info on this. Thanks for any help.
