I received the Kworld ATSC/QAM TV box you recommended. How do I hook it up to my Sanyo tv? Also how do I change the channels and volume? On the TV box it has a USB port, the colored video and audio ports, a PC port and a monitor port. I have the cable hooked into the cable in port but I need to know what else I have to do to make my tv work. The TV box doesn't have a HDMI port.
