What if:

3. I'd like to stream videos with DTS surround?

Apple TV 2 would handle DTS audio. A workaround here is to convert DTS to ATV supported audio formats: HE-AAC (V1), AAC (16 to 320 Kbps), protected AAC (from iTunes Store), MP3 (16 to 320 Kbps), MP3 VBR, Audible (formats 2, 3, and 4), Apple Lossless, AIFF, and WAV; Dolby Digital 5.1 surround sound.
