does anyone know how long it will be until local channels are prodcast in HD through a Direct TV HD receiver? I dont want to have to switch to Comcast but if they offer Local and more additional channels in HD without having to front hundreds of dollars and additional euipment i dont see how i can stay with direct tv despite comcasts bad service. Please advise. I can hang in for a few months but having a nice new HD ready tv and not being able to use it is killing me.
