Does anyone here know of an .m2ts capable reencoding program, which can reencode to .mkv, and which ALLOWS SELECTION OF THE AUDIO TRACK WANTED?

I, too am looking for a "one click" solution to converting M2TS to MKV. I found the following which does claim to allow you to select the audio file. Does anyone here have experience with this program?: http://www.icoolsoft.com/m2ts-converter/

Thanks!

I meant no offense. I've read this entire thread. txmuxer has been brought up several times. It obviously takes some know-how and several steps. I quoted Mummyscurse who was looking for a one-click solution. I was searching for such a solution as well. Hence the reason I used the term "converter".

I do appreciate your constructive input, though.

I thought this process was really easy; granted I was not doing anything fancy. Also, assumes that you have the Haali muxer installed.

I used eac3to like this:
eac3to.exe c:\\images\\movie c:\ emp\\movie.mkv

(c:\\images\\movie is the path the a blu-ray disc that I ripped)

The above created c:\ emp\\movie.mkv as well as some additional files with the audio, subtitles. The audio file had the extension .dts

The next thing I did was to run MKVMerge like this:
mkvmerge.exe -o finalmovie.mkv c:\ emp\\movie.mkv c:\ emp\\movieaudio.dts

The result was a MKV file called finalmovie.mkv which was had the audio stuck back into the container.

So, I have been trying to use tsMuxer to demux my m2ts files, and then using mkvmerge to create the mkv file. However, this is really not decreasing the size of the files, as the h264 video files are still rather large, and comparable to the 20+GB m2ts files I have. Am I missing something? I got the WD Livewire Powerline in hope of streaming my videos, but it wasn't working with my m2ts files, so I was hoping making them into mkv's might help. Let me know your thoughts. Thanks.

Neither tsmuxer or mkvmerge do any additional compression, so result files of the same size is expected. You'd have to use something like Handbrake to compress them further.

New mkvmerge supports m2ts directly, so you don't need to demux them anymore. mkv uses less tech info - saves ~5% of disk space. One file, compact container, signed tracks, chapters etc. But don't try to put VC-1 interlaced into mkv.

I am testing converting my Blu-ray folder rips to mkv's to save space by getting rid of audio I don't need.

I was curious when I did a test and found a 37,137,524,736 byte m2ts file converted to a 34,373,169,725 byte MKV.

For the test I used all audio tracks. is MKV really 7% more effecient at packing the same data or did I do something wrong. I am testing with dvdfab blu-ray ripper with mkv.remux profile.

Yes. It needs a LOT less headroom. Everything went fine.
