Now do I have anything to gain from this DDL for old DIVX movies that only have a stereo track? Today I just pass the stereo track through my DPLIIx encoder in my Pre/Pro and I get a very convincing 7.1 surround sound. Will it be better with DDL?
Ideally, yes its best to stay digital. The problem arises when dealing with DDL or to a lesser extent, DTS interactive.
Example. You have a DVD in Dolby Digital (or in DTS). When you have Dolby Digital Live enabled what happens is the multichannel signal is decoded in software, then recoded by the prelude and sent to your receiver to be decoded AGAIN then sent to the speakers. This extra step of recoding degrades the quality, for DTS sources, it really degrades the quality. Now later, the card will apparently have a HDMI pass through to enable 7.1 digital PCM to be sent to your gear thus eliminating the second encoding step and preserving a digital signal. This is overall the best choice, but requires a yet to be released adapter.
To answer your second question, its one of the points Ive been complaining about for a while now here. The short answer is no. DDL will do NOTHING to help with any 2 channel sources you already have. This is because the geniuses at Auzentech think that CMSS-3D is the ultimate sound experience apparently and DPLIIx isnt needed because of it. IMO, for now you will get far better 3D sound from 2 channel sources using your receiver's DPLIIx decoder. However, I havent tried with the latest drivers, but before, again Auzentech/Creative geniuses at work here, the SPDIF port is a raw feed and is not allowed processing from CMSS-3D, Crystalizer, EQ, or EAX. At least you can adjust the volume, which is more than you can do with DDL.
-DeathCom <- currently running integrated sound again due to new RC4 drivers, Teamspeak, and my mic not getting along. Deciding if its worth it to take a $40 hit to return the card entirely.
