Izithombe ongazirekhodile, ozenzayo noma ozibhumele ngaphandle azikhuselwanga ziguqulwa ngokuvamile; ukuthenga okusemthethweni akuzokwenza, futhi akukho oguqulelayo angaba nesiqiniseko sokuthi kungashintshwa. DRM-ikhuselwe M4V ukuthenga ngeke kushintshwe yinoma yini; kuphela M4V izithombe ezingakhuselwanga ziguqulwe, futhi abadlali Apple-ayikho njalo kufanele ubanzi kuthiwa.

WMV ngokuvamile ibuyela emuva ku-software decoding ku-hardware efanayo - u-CPU ophezulu, isisetshenziswa esipholile, namafreyimu akhuphuka ku-4K material. Uhlelo oluzosetshenziswa, M4V luyi-container ephephile yokuhlala kuyo.
