Removing Subtitles With MKVMerge

If you have subtitles in an MKV file that you want gone, you don't have to re-encode the whole thing. Simply open in MKVMerge, choose the track you want to remove (the text track if you want to remove subtitles), uncheck it, and remux. It'll take a few seconds and won't re-encode everything else. While there, you may want to make sure Compression is set to "none" explicitly on the extra options tab for each track to ensure maximum compatibility with things such as PS3, etc.
