I think some do, but you'll have to check the disc specs; a site like Highdefdigest.com is good for this purpose. Like regular DVDs, not all do, so you've got to check. For the most part, though, they should have some form of uncompressed audio (PCM, Dolby TrueHD, DTSHD-MA). If you can't accept uncompressed audio, your player should be able to extract the regular version in the case of the latter two (Dolby Digital, DTS). As for getting the 6.1 signal, it depends if the DTSHD-MA encode is in 6.1.
