OPA's remastered Trigun from DVD. The only change is that it's remuxed with default Japanese audio and English subtitles so that those who prefer it this way won't need to change the settings each time an episode is launched. See original torrent at [\#117112](http://www.nyaatorrents.org/?page=view&tid=117112) for more info. To modify default audio and subtitle tracks in your existing MKVs, download MKVMerge from http://www.bunkus.org/videotools/mkvtoolnix
