Anyone in NYC demo having this issue? For about 2-3 weeks now whenever I record on chs 2-11 (HD) I get blocky content and it freezes up until I FF, and in some cases I have missed up to 5 mins worth of programing. THis is on an HR20-700. This DOES NOT happen on any of my D*Tivos (SD), nor does it happen when I record off of the locals in the 80s. It's gotten to the point where I've swithed over most of my SLs to the 80s.
