Nah, the more channels they can cram on, the more money they get for it.
So far we have had four digiboxes, two that didn't work properly and had to be brought back and one that died after a year. Televisions and video recorders last much longer. So for people who have difficulty affording a digibox, there is also the problem of having to replace ones that die, and it will still only give one channel at a time, unlike analogue where you can record, and watch a different channel, while the kids watch another channel on a different TV. With digiboxes you either have to go for the very expensive ones that can decode multiple channels, or buy lots of digiboxes.
One piece of advice folks. Get a box with buttons so you can change the channel manually. Kids always lose the zapper.
