Unfortunatly, the channels below 60 are in their old analog system, there is no digital sound or picture for these channels with a few exceptions. (I believe AMC and Comedy Central are two.) I have a reciever that is set to play the analog if no digital signal is present, if you do not have this, then your only choice is to switch to analog. You only get digital if Time-Warner broadcasts it, unfortuatly, on these stations they don't.
Any word on those free On-Demand channels?
