LG液晶电视上播放mkv显示"不支持的音频格式"

下了一个高清诸神之战(Clash.Of.The.Titans.2010.BDRip.x264.DTS-WAF.mkv, 2.1G)，放到家里的LG液晶电视上结果显示不支持的音频格式，一查才知道，原来包括LG液晶电视在内的很多电视不支持DTS(Digital Theater Systems)，虽然很多播放软件支持。所以要在电视上看必须做一些转换才行。

查了一下，这个直接用mkvdts2ac3脚本的方法比较适合Ubuntu用户:<<Converting DTS to AC3>>(http://www.networkedmediatank.com/wiki/index.php/Converting_DTS_to_AC3#Step_by_Step)。但是文章里的mkvdts2ac3链接已经失效了，得自己去找，比如这(http://github.com/JakeWharton/mkvdts2ac3).

需要安装的软件:
- mkvtoolnix
   sudo aptitude install mkvtoolnix

- dcadec
   wget -c http://download.videolan.org/pub/videolan/libdca/0.0.5/libdca-0.0.5.tar.bz2
   tar jxvf libdca-0.0.5.tar.bz2
   cd libdca-0.0.5/
   ./configure
   make
   cd src
   sudo make install

- aften
   sudo aptitude install aften
