I can use Handbrake and get my files to play just fine in DTS-HD MA but when I try to convert anything from Dolby TrueHD sources, it either downmixes or converts to another program.
I have tried Handbrake and DVDFab to no success. Any other idea besides playing the 25 gig native file for Dolby TrueHD? (That works fine by the way)
Seems like a handbrake support forum question...
Just wondering if anyone here has run into any good ways to do this since HD audio support has been a long sought after feature...
a) transcode original m2ts video stream [orig.m2ts] to x264 using handbrake - this will result in an video-only mkv [vid.mkv]
b) use mkvmerge to combine DTS-HD or Dolby TreuHD audio stream + all HDMV (subtitles) with transcoded mkv file
[orig.m2ts] + [vid.mkv] = [finished.mkv]
End result will be an mkv with the transcoded video + HD audio + subtitles into a finished mkv.
This is what I have done hundreds of times.

Are you using the "auto passthru" audio option, see

I am running Handbrake off the nightly ppa and this 'may' now work properly for both DTS-HD and Dolby TrueHD, but last time I checked - mid-2012 I think - it didn't seem to pass the HD audio through as expected so I just stuck with the extra step of remuxing with mkvmerge.
IIRC it seemed to have issues passing the selected audio stream onto the finished product / mkv.
Have you tested this recently?

My main desktop is on the Lucid PPA which doesn't seem to have moved since April...I'll try this on a newer desktop I guess. Maybe its fixed now.
I've never tested it, just what I found with a quick Google. Personally I use MakeMKV to keep the uncompressed video & audio.
OK, no problem.
I'll maybe test this out again on newer version of Ubuntu / newer build of HB off the PPA and let you know if its working properly now.
Would save an extra step with mkvmerge.
I realize this isn't a HandBrake/MakeMVK support forum but I thought we could all collaborate here, so I appreciate the conversation.
Here are the different methods I am using:
Step 1 - Blu-Ray to .MKV using MakeMKV. That creates a 20-30 gig file that plays in XBMC just fine with Dolby TrueHD or DTS-HD
Step 2 - To Shrink the file, I have tried using HandBrake and DVD Fab Blu-Ray Ripper. Both will do DTS-HD fine. No go on passthrough for Dolby TrueHD. Both methods downmix it regardless of setting..
I will give MKVmerge a whirl!
MKVTools has pass-through support for Dolby TrueHD (and can also re-encode the video to lower rates to save space just like Handbrake), unlike Handbrake (their forums suggest it will get this support in the future, but I don't know when. It seems odd DTS-HD passthrough made it over a year ago and it can read TrueHD, but can't pass it through. I would have thought passing it through would be simpler than encoding it something else, but I don't know the technical details. Handbrake CAN pass-through DTS in M4V containers, though, which is pretty nice for being able to maintain iTunes/Apple TV compatibility (it just ignores the DTS track) while XBMC (Frodo and newer) can read the DTS track. Ironically, MP4Tools by the same author as MKVTools cannot pass-through DTS into a M4V container, so I have to use Handbrake there.
MKVTools and MP4Tools are nagware (minor features like queues disabled until you register and a few second nag when you open a file), but this doesn't stop you from using the actual tools. They're only $6 anyway. MP4Tools fixed container issues that some other encoders somehow created without touching the video (i.e. Apple TV 2 wouldn't reliably play them while XBMC would, but after re-packing the the container with MP4Tools while changing no settings, just using pass-through fixed the issue, whatever it was so it was worth $6 to me, personally). I'm thinking about registering MKVTools as well since it can make my MKV files smaller and still pass-through TrueHD.
