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

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.

Here is some reading for you :
