Abathengi bama-DVD ebangeni labathengi bonke banamandla okudlala izinto ezivela kumthombo we-Dolby Digital 5.1, futhi abaningi bangadlala imithombo yomthombo we-DTS uma isetshenziswe ngamukeli we-AV. Noma kunjalo, amarekhodi e-DVD anemikhawulo ye-analog stereo kuphela yokurekhoda umsindo, okubekwe ikhodi ibe yi-Dolby Digital yesiteshi ezimbili. Ukukhishwa kwomsindo orekhodiwe kungatholakala noma ngemiphumela ye-analog stereo noma imiphumela yomsindo wedijithali yomrekhoda we-DVD.
Nakuba amarekhodi e-DVD amanje angakwazi ukurekhoda kumsindo we-Dolby Digital noma we-DTS wesiteshi esingu-5.1, uma isetshenziselwa isamukeli se-AV enamodeli angu-Dolby Prologic II kanye / noma i-DTS neo: 6, ukurekhodwa komsindo womzila wesiteshi kungenziwa kabusha kwisiteshi 5.1 noma 6.1 insimu ezwakalayo, noma ayinembile njengomthombo wokuqala we-Dolby Digital noma we-DTS soundtrack wokuqala wesiteshi esingu-5.1 noma 6.1.
Isizathu salokhu kuhlangene kabili: Njengoba awukwazi ukurekhoda (noma akufanele ukwazi) noma ukukopisha ama-DVD futhi kunomsindo wesiteshi esingu-5.1 noma 6.1 otholakala eminye imithombo ukurekhoda, akudingeki lokhu umsebenzi (nakuba lokhu kuyashintsha njengoba ikhebula elingaphezulu kanye nesistimu ye-satellite idluliselwa ku-Dolby Digital 5.1).
Noma kunjalo, isici sesibili mhlawumbe sezombusazwe ngaphezulu kunezobuchwepheshe: ngisho noma uphumelele ekwenzeni ikhophi yevidiyo ye-DVD, uvinjelwe ukwenza ikhophi yomsindo weziteshi eziningi, ngaleyo ndlela ikuvimbele ekwenzeni ikhophi "eqondile" ye-DVD eqoshiwe e-DVD engase "idluliselwe" njengeyokuqala.
Okokugcina, kufanele kuboniswe ukuthi kube khona izibonakaliso ngabakhiqizi abambalwa mayelana nokufakwa okungenakwenzeka kwamarekhodi e-DVD anekhono lokuqopha i-Dolby Digital yesiteshi esingu-5.1, kodwa akekho okwamanje oshaya amashalofu esitolo.
Ngenothi elihlangothini, i-Sony ikhiphe amanye amakhamera nge-5.1 yesiteshi se-Dolby Digital sokuqopha - ngethemba ukuthi lokhu kuzokwenyula kuma-DVD recorders.
