component VIDEO (note, not AUDIO), the 3 cables, are Red Blue and Green are VIDEO circuits. do you have an additional audio cable plugged in? if you don't, of course you have no sound. lol
what do you have set up for audio?
if running stereo with component, you should have 5 cables.
if runing 5.1, you should have 9 (or 4 if you are running a digital output coax or optical on a single wire)
the reason your dvd player had a switch like that is so that most people don't own a 480p capable tv.... and they feel that the ones who DO will know more about the dvd settings to make it go progressive than the ones without it.
