Mkv to blu ray without audio loss.

[batmeat]

I'm sorry if this is posted elsewhere. I can't seem to find exactly what I'm looking for using the search tool. The results I find are over my head. I'm looking for a way to burn my Mkv files directly to blu ray without a loss in the audio streams. I don't really want to convert them to blu ray format then burn them. Direct burn is preferable. A bunch of my Mkv files have multiple audio streams for 5.1 and 7.1 surround sound. I don't want to lose that when I convert and burn to blu ray. Also, any guides that can be reccomended is appreciated.

I have found programs to convert, but all of them change the audio to 2 channel stereo.....not acceptable.

Forgot to add that i don't mind paying for software to do it.

Well, if I understood you correctly, all you want to do is to write the files directly to disc without complying to any standard or HW compatibility etc., right? In that case, any burning program that can write Blu-Ray discs should do, maybe even the built-in one of Windows (might depend on your version, don't know if XP can do that but Vista/7 should). Personally I'm using this one: http://cdburnerxp.se/ (free) but of course you can also use other or proprietary programs for that.

I don't want to create a data disk. I want to burn the Mkv file to blu ray and have it work in my blu ray player. The software would need to automatically convert the format so it's compatible with blu ray movie players.

Without knowing what type of video and audio you have in your MKVs there's little help you can expect.
Blu ray has several restrictions for video and audio and you might have to re-encode the video to make it compatible.

[blubb444]

Well, in that case you'll probably have to (lossily!) re-encode, unless you know that both your video and audio streams are BD compliant. You can find a quick overview here: http://en.wikipedia.org/wiki/Blu-ray_Disc#Software_standards According to that, up to 7.1 (8 channel) audio is supported in some formats. But there are still many more limitations, especially in the video stream (Bitrate, P-/B_frame, level, buffer size... limitations).
Maybe you could post a MediaInfo analysis of your file?

Use your original blu ray with BD-Rebuilder. :)

I'm not aware of any software that can directly burn MKV to Blu-Ray (but I don't know every software, so that doesn't mean much). Some people use tsMuxer first and then their favorite burning software (like ImgBurn), but as the others have already said, it's not 100% Blu-Ray compliant and might or might not work on a given Blu-Ray player, but in exchange it is lossless and fast. If you want 100% compatible Blu-Rays you have to re-eencode the video (http://forum.doom9.org/showthread.php?t=154533) first. The audio does not have to be re-encoded, though, if it is compatible. (Like AC3 or your DTS track)

As you can see, when you allegedly transformed your BDs into MKV you lost the BD compatibility.

IIRC, the hunger games is a BD50, that means some 30-40GB are reserved only for video. So your MKV already had suffered a lossy reencoding, and you'll have to reencode it again, for the reasons indicated in the quoted passages.

So use the advice given by Groucho2004 :)

[batmeat]

Hmm. So this file isnt blu ray compliant? I bought it via a digital download, so it's probably an illegal movie service. This is good to know.
