mkvtoolnix 2.0.0 released
Hey users,

I'm proud to present you version 2.0.0 of mkvtoolnix. This release contains new features like support for AVC/h.264 elementary streams (both single files and from AVIs); proper support for MPEG-1/-2 videos without the ugly blockiness; support for extracting MPEG-1/-2 video tracks; use of "simple blocks" with subtitles has been fixed; tons of usability enhancements to mmg; and the usual list of smaller bug fixes.

Regards,
Mosu
