I have few files that I did retrieve from webpages, and saved as MKV files.
VLC play them without problems, but when I load the file either in the Windows video editor, or in Power director 13, the video play but there is no audio.
I am not sure why I can't even convert the file from VLC, since even using the conversion engine that is integrated in VLC, the resulting file has video but no audio.
My understanding is that if the video player can play it, then the system has the right codec, so why neither windows video editor nor Power director 13 are not able to play the audio?
