I'd have less of a problem with the adverts if they were placed in between scenes, ideally by a human so that they don't interrupt the flow in a distracting way (ie, lulls are fine, creating a fake cliffhanger is fine, cutting to the adverts while a character walks from one room to the next isn't).
I'm definitely much more pro places like BlinkBox and SeeSaw that reward the property owners than places like DailyMotion where you can see every extant episode of Doctor Who with less intrusive adverts but so as to make some completely unrelated people rich.
