There are 2 types of DD+ or eac3.
The old eac3 version used on HD-DVD has no core!
DD+ was mandatory on HD-DVD. Such audio streams have to be completely re-encoded, they are not backward compatible.
Probably the software is a bit outdated, because BD mostly use DTS.

With eac3to I never could demux a core from eac3 (to ac3). But I could create a multichannel wav for reencoding to ac3.
You can't see from what source (HD-DVD, BD) the mkv comes. (OK, there are no 3D movies on HD-DVD...)
DD+ from BD or TV is backward compatible. If you have an AV receiver with HDMI 1.3 or later, you’ve already got support for DD+.
Hope you have the right test stream.
