Hello-

I just purchased a Sharp 64LHP5000 HDTV and have connected to DirecTV via a Hughes HIRD-D45. I've also hooked up a terrestrial antenna for local digital broadcasts. My question is how do you know if you're getting HDTV via DirecTv? The only feed I have personally connected to the built in decoder is the antenna for local broadcasts. How do you get HD images out of DirecTV? Is anyone out there familiar enough with my model of TV to tell whether my DSS connection via the analog side of the HDTV is internally connected to the digital decoder? How does the IR mouse fit into this? Any input is greatly appreciated.
