I got this from asking UNC-TV about the holdup on HD being on DTV. This was the response. So is this the absence of an agreement or has this particular PBS channel not come up on DTV's list yet? Answer to my email to UNC-TV UNC-TV is transmitting in High Definition today via DTV over the air. At this point, the decision to provide our signal to their customers in HD is up to DirecTV. They are providing a downconverted signal today. We work together with them to try and make this happen as soon as possible, but the decision is up to them.
