Kudesktop yamanje elahlekile; ku-smartphone, i-laptop edala noma i-smart TV ivela njengefreyimu elahlekile, umsindo we-fan nebhethri elilahlekile. Ukushintsha kufomethi exhaswe yi-hardware kususa izinkinga zonke. Isihloko seDivX yi-MPEG-4 Part 2 video, sivame ukuboshwa ku-AVI, nge-MP3 noma AC-3 umsindo ohambisana nayo.

Ukuphela kwephutha elincane yifomethi ezimbili ezikhona ngokusemthethweni ibhokisi elifanayo ngaphansi kwezinhlamvu ezahlukene — futhi ngisho lapho ukuphinda ubhale kahle kuphephile kunalokho ukushintsha igama.
