If I connect to the RF-out from the digital set-top box, I can use mplayer tuned to channel 3 to watch TV but I'd like to be able to tune from the cable directly. Not sure what to try next.  Here's the results of my test:

Also,  do NOT use the rf out from the cablebox -- you wont get any
digital services that way.  You must use the cable feed coming in
directly from the wall / street.
