Abarekhoda bebakala bama-DVD bakala bonke banakho ukudlala izinto ezivela kumthombo we-Dolby Digital 5.1, kwaye abaninzi banokudlala imithombo yomthombo we-DTS xa isetyenziswe ngumkeli we-AV. Nangona kunjalo, ii-DVD ezirekhodiweyo zineempawu zomsindo we-analog stereo zokurekhoda umsindo, obizwa ngekhowudi ezimbini kwiDolby Digital. Imveliso yomsindo orekhodiweyo ingafumaneka okanye ngokuphuma kwe-analog stereo okanye iziphumo zomsindo wedijithali werekhodi ye-DVD.
Nangona iirekhodi zeDVD zangoku zikwazi ukurekhoda kwi-audio ye-Dolby Digital okanye i-DTS audio channel, xa isetyenziswe ngomsitho we-AV eneenkcukacha zeDolby Prologic II kunye / okanye i-DTS neo: 6 abaprofeti, ukurekhodwa kweevidiyo ezimbini kunokubuyiswa kwisitishi esingu-5.1 okanye 6.1 kwintsimi ephilileyo, nangona ingachanekanga njengento yokuqala ye-5.1 okanye ye-6.1 ye-Dolby Digital okanye i-DTS soundtrack.
Isizathu salo sihlandlo ezimbini: kuba awukwazi ukurekhoda (okanye akufanele ukwazi) okanye ukukopisha iiDVD kwaye kukho umsindo wesiteshi esi-5.1 okanye 6.1 ovela kwiminye imithombo ukurekhoda, akukho mfuneko enkulu kule Umsebenzi (nangona oku kuguqulwa njengokuba ikhefu enye kunye neprogram ye-satellite idluliselwa kwi-Dolby Digital 5.1).
Nangona kunjalo, into yesibini mhlawumbi iphezulu kwezopolitiko kunezobugcisa: nokuba ngaba uphumelele ekwenzeni ikopi yevidiyo yeDVD, unqandwa ukuba wenze ikopi yesandi se-multitrack, oko kukuthintela ukuba wenze "ikopi" yeDVD kwirekhodi yeDVD enokuthi "idluliselwe" njengento yokuqala.
Ekugqibeleni, kufuneka kukhonjiswe ukuba kukho izibonakaliso ngabalingisi abambalwa malunga nokufakwa kwamakhompiyutha e-DVD kunye ne-5.1 ye-Dolby Digital yokurekhoda ukukwazi ukurekhoda;
Kwiphepha elincinane, u-Sony ukhishwe ezinye iikhamera nge-5.1 yeDolby Digital yokurekhoda - ngethemba lokuba oku kuya kucoca kwi-DVD.
