Wow! I didn't realize that you had Dolby Media Encoder. That must have set you back a bit.
Dolby TrueHD is only optional for BD, so this is the probable explanation for the compatibility problems – not that I've ever experienced any. While it's not used as much as DTS-HD MA these days, it's common enough on BDs.
