MP4'S SOLUTION ! Work good for me

So for my mp4’s problem: there is 2 aac audio stream on the video file, so i use mp4muxer :click demultiplex tab chose one of the audio files then remove the one you dont want, so there is one left so it’s done.

After every mp4’s play perfect on the wdtv live. good luck :smileyvery-happy:
