PS3 HD Audio Downconverion?

[THizzle7XU]

Hello,

I have a plain old Sony amp that has an optical input. I'm fine with this as DTS 1.5 sounds pretty good to me. With the Xbox 360 HD-DVD addon, you had the option to downconvert to DTS or DD5.1 regardless of whether the HD audio option was DDTrueHD, DD+, or DTSHD. I left the option on DTS5.1 as it sounds better that DD5.1. My question about the PS3 then is what formats can you downconvert to with the different HD audio formats? I know DTS-HD MA contains the DTS core 1.5 downconversion, but what about the other formats like DDTrueHD or uncompressed PCM, or even straight legacy DD5.1? Some of the BD movies that come to mind are the first two Spiderman movies (only DDTrueHD on the disc) and the Ocean's movies (only legacy DD5.1). Can the PS3 downconvert the audio on these titles to DTS 1.5mbps? Thanks!
