I have read over at Tivo community that soon all SD locals will be moved over to a new satellite which is MPEG4 soon. At that point all local SD channels will not operate on existing Diretivos and I would also assume older directv receivers. Is this true? I would think it would cost Directv a lot of money to swap out the millions of standard receivers that are not capable of receiving MPEG4 signals.
