Conversion of dash files to mp4 file format

Unfortunately, there doesn't seem to exist a reliable way how to convert DASH (Dynamic Adaptive Streaming over HTTP) files to the original MP4 file. Although some video converters falsely advertise to support dash to mp4 conversion, it usually does not work as expect.

DASH files are meant for watching only (like on Youtube) and not meant for downloading. At best you will be able to playback them using a multimedia player, but audio track is not included in .dash files.
