guys im stuck i purchased the Kanex adapter http://www.kanexlive.com/products/item.aspx?id=3495 and i want to connect my MacMini to my Philips 8654 LCD tv but i dont have any home cinema stuff, so its only gonna be connected to my LCDtv, so i want to ask a few things: 1. Where do the usb and optical plugs should be connected to? And what are they used for? 2. Can i connect the usb plug only so i can have sound or must i use the optical too? In the kanex url it says that audio cannot pass through the usb, does that mean anything? 3. Do u think its wiser to purchase the other Kanex model http://www.kanexlive.com/products/item-id-3323.html since i will only be connecting the mac mini to my tv? 4. Can the optical plug be connected to the tv (http://www.p4c.philips.com/cgi-bin/dcbint/cpindex.pl?ctn=42PFL8654H/12&slg=en&scy=GR) Im swamped-help!
