Just wondering what each one was for. Also If I keep AC3 5.1, can I get rid of the two AC3 2? Obviously I'll get rid of the french. Example from a new movie. AC3 5.1-ch english AC3 5.1-ch french AC3 2-ch english AC3 2-ch english Do I need the 2ch?
Keep the 5.1 and get rid of the rest. Unless you have a movie that only has 2channel (stereo) sound then it is not necessary to keep it. Even if you do not have home theater your TV will demux down to 2 channel. If you keep it you run the risk of getting Directors Comments instead of movie audio.
