I read through that, it doesn't tell me much. I also did search for it, but I only found the .deb files. I can't seem to find the installer program. Also, it's not on repository. How safe are they? From what I've seen so far, I'd assume that each gstreamer file is it's own individual codec, am I correct? If I am, I can't seem to find the codec that will allow mkv to be played.
