There is no magical correct period of time after a modulation and codec decision is made during which it is not possible logically to consider scrapping them and starting over. Taiwan did it soon after picking 8-VSB. It could be a month, a year, ten years or a century. There is no period of mourning or the wearing of black or a period in which to write off or work off the bad investment. At any point after the original decision it is possible that a rational look at the situation would dictate a change, all things considered. I submit that at any moment since the decision to use 8-VSB and MPEG2 it was rational and logical to consider scrapping them both. I believe that the arguments to do so have only increased minute by minute since then and will continue to do so.
