And it isn't the Dish that is MPEG4 compatible per se. It is the receiver. That being said, if you want all of the HD channels you would need a satellite that points at either 61.5 or 129 (in addition to the 110/119 locations). Right now the available MPEG4 receivers are the 411/VIP211 (single tuner standard receivers) and the VIP622 (dual tuner DVR receiver). Lots of info here on both.
