I converted a couple of .mkv video's with MKVTools and added subs with Subler. I used pass Thru for Video with all movies and for audio I used AC3 5.1 and 2ch. AAC. I used all the same settings for the output files and none of the movies will play except for one. If I check the info in QuickTime it says that the total bitrate of the movie that plays = 0. All other movies have a total bitrate between 3000 and 5000. A little help please?
