i've posted a couple things on here in the past about problems ive been having with my local hd channels. i've had my directv hd package for about a month and when they came out they put up a new dish. i have problems mainly with fox and cbs on primetime. i dont know if its because i have the newer receiver or the dish has to be repositioned. its weird because its happened during the oc, house, prison break but not 24 or american idol on fox. has anyone else had any problems with philly hd channels. what should i do, i need some help.
