No problem. I can record other local HD stations with no problem. However, whenever I record WFTV HD feed their playback is choppy. SD WFTV is fine. There are others that have posted that have this same problem.
DirecTV along with others have reported that it is not a unit problem, but reception from that station.
In terms of why technically it isn't the HR20 I couldn't tell you. I would think if it was the HR20 I would be having this problems on the other HD local feeds.
