DVD-Audio, SACD, multichannel PCM, DD+, TrueHD, DTS-HD High Resolution, and DTS-HD Master Audio are all available via the multichannel analog outputs. That's exactly why it's such a good player for use with non-HDMI processors and receivers.

DVD-A is available from coaxial/optical as downmixed stereo (same as any other DVD-A player). SACD is not available at all (same as any other SACD player except the SACD-capable PS3's). DD+, TrueHD, and both DTS-HD's will output the lossy core DD/DTS track via coaxial/optical (same as any Blu-ray player I am aware of).
