If im using the Samsung t160 with a dish and antenna for HDTV, can i use DVI-D all the way from the sat receiver to the Marantz s2? I know that DVI-D is digital only. The directTv stuff is digital, Is the over the air HDTV broadcast considered all digital also? would I be able to watch directTv and terrestrial broadcast of HDTV using the DVI-D connection only? Thanks in advance for you help.
