I'm too interested in DTS support. If I understood things correctly this is pending to the availability of native code execution library from google (NDK). I noticed there is instructions on how to get it installed "unofficially" over here:

Played a couple of movies just fine over dlna, though one I couldn't get the audio to work.

Likely is DD encoded. Notorious issue with 2.1 Revue... Can you try to download hddvd_demo_1080p.mkv here:

and check if it ...

another question - what's the version of flash embedded in chrome?

could someone confirm if new media player supports:
- selecting alternative audio track when playing video (MKV)
- subtitles

Also, what's the build number (System settings -> about) of this leak?
