I'm thinking about getting the Apple TV and I was wondering if it's possible to connect both my TV and stereo to it simultaneously. If I use the audio from my TV I would just then need to connect the HDMI cable and I'll be all set for the TV? Would that then allow me to connect my stereo to the Apple TV so I could stream from my computer to it? I see from the tech specs that there is an optical audio port. Are there any optical audio to RCA converters? Thanks...
