I have moved this unit from a room with a HDTV cable box connection to my rec-room and connected the cable to TV as shown on page 22 of the manual, (via VCR). However, when I plug the cable into the VHF port, I get nothing. When I moved the connection to the AUX port, I have all of my cable channels. Also, my VCR doesn't play on any of the TV/Video settings regardless of which port I use.
