You'll see that the player's 5.1 analog outputs DO NOT put out Dolby TrueHD, Dolby Digital Plus, or DTS-HD. The only way uncompressed digital surround schemes are outputted is via the HDMI cable, and the A/V receiver has to be able to decode DD+, TrueHD, and/or DTS-HD.
Now it makes me wonder if the 5.1 analog outputs on HD DVD players are downconverted to DTS as well. That's what HD DVD does over the SP/DIF link, whether TOS or coax.
