I have a bunch of MKV files that I want to convert to M4V files. I recently tried converting the MKV files to M4V using Handbrake. But I ended up with a short audio file without sound. So I tried Subler to convert my MKV files to M4V, and the audio, as well as the video, are in language "Unknown". What's the problem?
