Okay, I have an Apple TV and a Sony DAV-DX375 DVD/stereo set-up. There doesn't appear to be any way to input 5.1 sound into the Sony DAV-DX375, but I'm wondering if maybe I'm overlooking something. Does anyone have any ideas? The Sony has two analog/RCA inputs and one stereo-mini input (on the front, usually used for iPods or things like that).

I believe all you do is run the AppleTV sound into the left and right RCA jacks on the stereo and set it up for surround sound. Reading Wikipedia, it appears that the five channels are encoded on a two-channel source (specific part here).
Now, the AppleTV specs specify "Dolby Digital 5.1" so maybe 5.1 surround sound only come from the optical audio output.
That's what I can offer; hopefully somebody else can elaborate and/or correct this.

No, you are not overlooking anything. The home theatre system that you bought does not have any digital inputs and therefore cannot receive 5.1 sound.

Apple TV only outputs Dolby 5.1 from the optical port and HDMI. Your receiver would need these to decode the signal.

Well, in addition to using the optical port or HDMI, you need a source that is truly Dolby 5.1.
There are two forms of Dolby 5.1, one is where all the channels get encoded into the two stereo channels, but are NOT kept as dedicated channels. Those will sound kind of meh.
If you truly want DVD quality 5.1 surrond sound (5 dedicated channels, called Dolby AC3), you'd need to use Handbrake to encode with with AppleTV setting, AND (very important), change the Codecs setting to (AVC/H.264 Video / AAC + AC3 Audio." Not that this will only work with AC3 sources, obviously.
Apple now also sells some few movies with dedicated 6 channels. I'm not sure how to know though which ones these are.

Thanks for that, I was unsure about the audio codec setting.
