Confused about mkvs with hd audio

[VistaVick]

Everything I have read suggests that the latest versions of makemkv preserve hd audio tracks and produce mkvs with dts-hd or dolby true hd. And I don't see any options in the program to do otherwise.

However, I have made backups of several retail bluray discs recently, most with dts-hd audio tracks, and none of the mkvs appear to have the hd audio tracks, they just play as dts.

But I am setup to play mkvs with hd audio. Following a nice guide, I am able with media player classic 64 bit to play m2ts files with hd audio tracks and it works great. I wanted some .mkv files to try. As an experiment, although it takes much longer, instead of using makemkv, I used tsMuxer to demux the DTS-HD track from one m2ts bluray file from a bluray disc, I used RipBot to convert the m2ts file to mkv without an audio track, and after RipBot did its thing I took the mkv RipBot made and muxed it with the DTS-HD audio track using mkvmerge GUI.

The result was a mkv file that played with dts-hd audio in media player classic. Unlike the mkv file makemkv made. The mediainfo program shows a dts-hd audio track in sheet view for the file I muxed, while it just shows dts for the file makemkv made.

Any idea why I am seeing these differences?

Not sure if it matters, but I am using windows 7 64 bit with ati 5700, and ffdshow audio and video codecs with mpcs internal splitter. I also have no problem bitstreaming dolby true hd or dts-hd from bluray discs to my onkyo receiver using PowerDVD.

Nevermind, I was forgetting to open the tree file options on the individual files, and the hd audio was not selected as default.

Glad to hear that, in fact, MakeMKV successfully generates .MKVs with HD audio for you ;>}
