More info?)
There is a differnet standard for digital HD tv between Over the Air
Broadcasts and Cable. Few Cable companys are allowing Over the Air signals
unaltered on cable. You must have a CABLE set top box to receive HD from
cable. I'm hoping this will change as more people have built in HD tuners
in their TV's. It won't hurt to "memorize" the channels on cable, you have
to do that anyway. If your cable company is more enlightened then some of
your channels will be HD. The only way to know this other than the
SOMETIMES obvious picture is to press the info button for that channel.
Digital channels will also not work with your HD TV tuner.
