is your sony vaio a laptop or a desktop? Cauze if it's a laptop, you should forget about it. It it has the right port, that laptop must be useless....
Umk...this works for any desktop. Get a Graphics Card w/ TV out, then find a female video in to male TV-out cord, then your'e golden. Oh...and plug the white cord into the sound imput (i dunno, probably on the sound card) and the red one's for stero sound (right?) and it doesn't matter.
For TV in ports, buy an RF switch for your System (about $20-30) and you're golden.
Turn the system on, and it should work.
