If you were waiting for the new AMD OCUR CableCard systems to start shipping and maybe get one of your own, you are going to be waiting a bit longer according to DailyTech.  They say that some bugs in the firmware and several cable operators are forcing them to halt shipments. 
AMD’s newest CableCard endeavor may have hit a snag.  Systems manufactured with the ATI TV Wonder Digital Cable Tuner have a bug that has halted shipments of the new PCs.

ATI engineers claim the bug is very minor. “The bug occurs when the TV Wonder Digital Cable Tuner attempts to sync signal on an all-digital tuner,” said one AMD Taiwan engineer. 

The bug seems to affect those who have TV Wonder Digital Cable Tuners with specific all-digital providers.  With the current firmware, users will get a “no signal error” after inserting the CableCard.
