They have ... but the complaints were based on actual viewing not on someone telling viewers that PQ was bad based on a number. That's why I mention "SD Lite" ... which has been the standard for DBS since the beginning. PQ issues on SD are caused by compression. Some channels are overcompressed when E* receives them - others need tweaking from time to time to make sure they have enough bits available for acceptable PQ. But at least the complaints are based on actual viewing.
