M4V is a video container that stores audio and video data used for iTunes files. Files of this type may be protected from illegal viewing and copying with Apple FairPlay DRM. In this case audio or video files should be bought in iTunes store. Not protected files can be viewed almost in any modern player because the format is based on MPEG-4 structure.
DCX file is a multi-page image file developed by raster file or bitmap file formats. It is generated fro PCX files, so it has a small header that shows the .dcx then a sequence of .pcx data. Popularly used by applications to create and send multi-page fax files.
