Some channels are already notorious for scheduling ad breaks with little regard for natural breaks or critical points in shows - just look at the commercial digital channels when they show films or repeats of BBC programmes. Even specialist film channels such as Film 4 are apparently incapable of showing entire films without regular and often inappropriately-timed ad breaks.

I'll be highly unlikely to sit through something containing much of this. The concerns for impact are a bit silly too, some people like watching adverts, and those that don't probably always skipped them. I often tape stuff on video to watch later, fast-forwarding through the adverts. If I'm watching something as it's broadcast I flick through other channels or at the very least hit "mute".
