Chuck, this must seem like a cake walk after all the issues you had with WBBM-DT back in Chicago? If you ever peek in on the Chicago OTA section over at AVSFORUM you'll see folks are still fighting the battle on getting a signal, even the D* feed has been having issues lately.
You are right. But I can assure your they are working hard to get past the problems. I believe BBM has another HD channel to go to after the transition in 2009 that will resolve the vast majority of the issues they face today on channel 3. Trust me, they want it to work too.
