I saw a post on CNET that a couple of people who bought Sony Bravia TV's with internal receivers purchased HD antennas to pick up the local HD stations. Does anyone know how well this works or should I go with Directv's HD DVR? I want to keep my DVR but don't really see the reason to spend $400 for an HD DVR and then $10.00 more a month for the few stations they have in HD besides the local channels.
