Izi zikutanthauza kuti kuchokera ku luso laukadaulo, polumikiza chingwe kuchokera ku gwero loyenera kupita ku cholumikizira choyenera, wolandila wailesi yakanema angapereke kulandila kwapamwamba kwa gwero lazizindikiro. Pochita, kulandira kanema kumakhala kovuta chifukwa chakuti khalidwe la chizindikiro chomwe chikubwera sichingakhale chokwanira. Izi sizidzakulolani kuti mupeze chithunzi chabwino ndi phokoso. Mwachitsanzo, izi zimachitika ngati kuwongolera kwa satellite sikunayende bwino. Vuto lina ndi lokhudzana ndi kubisa kwa tchanelo. Nthawi zina, kuti muwone mapulogalamu ena, muyenera kulipira kwa wothandizira. Idzapereka wolandila yemwe angathe kuwapatsa kulandira kwawo kapena khadi ya CAM, yomwe imangochotsa kanemayo ndikupangitsa kuti iwonekere. Kugwiritsa ntchito DVB S2 kumapereka ogwiritsa ntchito zotsatirazi:
