Izi ndi chifukwa chakenso mavidiyo ndi zochepa kwa zimene ali ndi chifukwa chake kusintha iwo ndi nthawi zambiri chinthu choyamba aliyense amachita.

Mu kutsatira yemweyo, ayi. The format anafotokozedwa m'madera amodzi kapena awiri, kotero surround mix ayenera kuikidwa pansi stereo kuti agwirizane - amene ndi bwino kwa headphones ndi foni okamba ndi zoipa kwa chilichonse kumbuyo kwa home cinema wolandira. Ngati chiyambi ali multichannel mix woyenera kuteteza, kusintha mu chonyamula kuti amayendetsa izo kuposa kulola downmix kuchitika mosasamala.
