I have a motorola dcx3400 connected to comcast in new jersey. For the last month or so I cannot get HDNet, HDNMV and On Demand at all. I've called comcast several times and they have refreshed my box several times without success. A serviceman told me that there was a problem with my dcx3400 box. I got a new box from comcast and I still have the same problem. I spent another hour on the phone with customer service and now I have a bunch of scheduled recordings set for channel 65535, lost all my series recording settings, and still cannot get the two channels and On Demand. Is there a fix out there?
