BEIGE  Beware - the license is tied to your machine so now I'm stuck using this on my mac mini...   
(Version 2.1)

JOSHMUNKEY  This is a jack-of-all-trades application, but a master of very little when it actually comes down to it. The handling of .ogm files is wonderful to see, and the ease of file extraction really sings to me as I am constantly tinkering with the streams of my files, but there's so many bumps all over the place that leave me scratching my head, such as a lackluster interface and feature set when actually converting files (a lack of automatic bitrate calculations becomes a bother, as well as the half-assembled height/width bar that leaves some of my .h264 files oddly squished when the original file under Quicktime has differing normal size and current size, natively).

In a way I suppose that I keep coming back to this application because the more efficient and robust ffmpegx has all but kicked the bucket and I am hoping to see the same sorts of innovation that that old and decaying application brought, but... maybe they are just two separate and differing things all together. It's a sad feeling knowing that I need to jump to a Windows partition to do even the most rudimentary of tasks with AVC files if I want exacting quality, but it just seems that for now that is the way it is.

(Version 2.2.4)

NED SCOTT  The reported updates on both macupdate and versiontracker say 2.2.3. The download link on the website gives you 2.2.1. The alternative download link (megaupload) and the version mentioned on the site now say 2.2.4. wat.  
(Version 2.2.3)

AIKOUSHA  I don't know what form of mkv files those who gave this a 5 were converting, but it wasn't x264 based...

I've been trying this on and off since it was version 1 of mokgvm2DVD. I had EXACTLY one conversion come through correct and easily on the video portion, but the subtitles were screwed up (tiny with no way to change the size or position, yup I know about the options button).

However, probably not due to the GUI or tools in this package, it can't cleanly convert any of the stupid matroska files I need to convert. I actually have to give these to people outside the company to deal with. The video that results from this and it's previous versions have stalls, drop outs, jumping blocks and in ALL cases now, have a really bizarre form of horizontal digital streaking. My guess this is due to a popular windows x264 (not a compliant H264) codec that has no Mac/Unix/Linux equivalent, and it screws up like this due to improper header information and something critical in the actual image processing that is not completely compliant with H264.

On top of that, nothing I have given this new version (MKV Tools), can even get the subitles to burn into the video. Since everything I deal with has subtitles of one form or another, this is a deal breaker.

I do like the fact that matroska files converted with this maintain audio sync correctly, even though there isn't a single player out there that can maintain sync while playing the mkv files I deal with, live.

I'm sorry I can't give this a recommendation, even if the main problem is most likely with the idiots on the Windows encoding side, but a Matroska converter that can't convert matroska files to make them watchable (regardless of whose fault it is), is fairly useless.

ANDY49  This does not convert mkv files on 10.5. It says complete within seconds.  
(Version 1.2)

HAGOUN  Mplayer is able to read mkv files quite well (containing rv9/10, h264 or wm9 video track).

Just download last xcode package to compile it.

Otherwise, nice to extract subtitles and other extras from mkv files

DOUG S.  Thank god someone finally did this! I'm sick of getting Matroska files when I download fan-subs and having to watch them in VLC player. Now I can use them all in Front Row!

Features: It does everything you'd want it to do and then some, giving you lots of options to have the final product suit your tastes perfectly.

Ease of Use: You just drop in the files, select the parts you want, and either extract or export. It's that easy.

Value: It's free. What's better than free?!

Stability: I've not used it extensively as of yet but from what I've seen it runs perfectly smoothly.

RANDYHARRIS  This program has been 100% successful in converting the few MKV's that I run across into playable XviD files. Other programs like ffmpegX and VisualHub choked on them, but not MoKgVm2DVD.

ERRORR  Works as advertised, easy to understand UI. Thank you for writing useful utilities and sharing them.
