Can't believe this; I've put together several HT systems, just got done troubleshooting a nasty hum in my SVS sub, and I can't figure out the Xbox cable system. My problem is, what cable pack do I need to see S-vid and hear a DD output? I see you guys posting about an advanced pack and a high def pack. Since my tv is not a high definition set, all I need is the s-vid cable. Besides, there aren't any component connections on my tv anyway. But, I also want to hear everything in DD. So, I need a coax or, the optical. Which cable pack comes with an S-vid and optical connection? The many posts I've read through, some of you guys are using the advanced pack and others, the high def. But then it seems like every person adds to their post that they have the optical cable. Is that separate? It doesn't come in a set? It looks to me as though the Xbox only has the custom audio/video port on it's backside. I didn't see anywhere to connect a separate audio cable. So, which one...advanced or high def for s-vid and digital audio? Thanks for any info you guys can give.
