It really isn't something to be excited about imo. From the one mix where I was able to compare it directly to DTS (HD DVD of Chronicles of Riddick) it was handily outclassed at the same bitrate by the DTS mix. In any case, it's a lossy codec and in this day and age shouldn't even exist in light of lossless codecs like TrueHD.

Yeah. To me, the issue is being able to tap into Dolby TrueHD. DD+ vs. DTS isn't a big deal IMHO.
