the timing, frequency and age of the repeats are the problem.
sure everyone plays repeats, not everyone can watch at the same time.
i remember seeing kids movies in the middel of the night/morning, or a movie from 19voetsek on at the same time every time the dstv is switched on.
adverts so frequent and long it breaks concentration and irratates, especially when its the same advert, every, single, time. not that its working, i cant even remember the adverts that were doing it, but i DO remember it was on dstv that i experienced it.
sky TV also playes repeats, heck they even syncronise adverts so if you channel hop its adverts all over, BUT their content is up to date, and their repeats are up to date and well timed, not always ancient. if you put the tv on at the same time, it will not be showing the same content.
