Onkyo HT S5100 doesn't convert signal. Need Help

[jk2008]

Hello all, I am very new to the Home Theater setup and I would need some help with ONKYO HT S 5100.

I bought this system when I was building my basement. I ran a component cable from this receiver to my Projector.
Now that the basement is complete I tried hooking the system up. I was able to to hook up a DVD player directly to the projector using the component cable in place but I was unable to do so via my receiver. I also tried the same with my PS2 and no luck. I think the receiver is not designed to convert the signals. If I am giving component input it is asking for component out. Which means I cannot use other media on this receiver. My PS2 gives me AV out which goes into the receiver but nothing comes out as I am running component cable only.

Could anyone please confirm if this receiver does not convert or is there something I am doing wrong.

Thanks a lot.
JK
