There's only one Analog audio out, there are 2 digital audio outputs.
You can use component with one of the opticals. Or, if you must use Analog for both, split the analog output.
Go to Radio Shack and buy 2 Y adapters for the audio outputs. Split your 1 audio out in to 2. I have this setup here in my office. Svideo/RCA Audio 1 to TV, RCA Video 1/RCA Audio 2 with Y adapter to Slingbox and RCA Video 2/RCA Audio 2 with Y adapter to ChannelPlus channel modulator. Works without a hitch.
