Yeah like I said above even sat tv providers Dish Network in the US and Bell Express in Canada don't follow the DVB standard completely for some reason. And DirectTv isn't even close.About the only thing that is similar is the use of MPEG 2 transport stream - that is the common base. Everything else... different.They must send it some how otherwise the cable boxes would not be able to display it. They don't follow the DVB standard?
North American TV seems very strange from an outsider perspective.
