So first real issue ( after some lost recordings in mid Sept during days of early software load). Local NBC recording of The Office last week had numerous blue screens, broken audio, frozen video etc, after 3 minutes just quit watching and deleted, sexact same behaviour on the other HR20 in the house, so I think it has something to do with local affiliate HD. Since I get NBC HD DNS as well I am going to have one DVR record on local and other always record on NBC HD. All my audio and video issues seem to be on NBC and NBC only more crackle and pops on local versus NBC NY
