There is a difference bewteen HDTV and just regular digital satellite. The problem is there are not very many channels broadcasting in Hi Def right now here in Canada...mainly sports. Get the regular ExpressVU for now until they have more channels being broadcast in HDTV. And stay away from cable....there Hi Def does not compare to that of satellite.
Also, there is a new hack for Bell so you can get all PPV and porn channels wide open

and no, don't ask me to help you with that
