Surround Sound cables

I have just bought the 2nd gen Atv, however my surround sound doesn't have an optical audio digital outlet, just the old RCA audio outlets, any suggestions on what i need to hook it up?

I'm no expert on the ATV 2 but I don't think there is anyway you can do it unless you can hook up your surround sound to the TV instead and have the TV output the sound it receives to the Surround Sound System.

The above would be one option if you're using HDMI to the TV. Use it's audio out to your receiver.

Second option would be an optical to analog converter similar to this one (stereo for about $25 or this one, 5.1 analog for about $250.
