My issue now is that sometimes, during playback, the DVR locks up. The display counter continues to display where it was up to and any timer-recordings in progress stop. I can do a soft-reset using the remote and the DVR takes approx 10 seconds to react to this. The DVR goes through a longer startup than normal and then resumes the timer-recording but as a new recording. The previous part of the recording survives. The recorded program we happened to be watching also exists and when replayed does not appear corrupted at any point. It would seem that there is either some kind of memory leak in the DVR or that something is triggering the lockup which I don't understand. As I can't replicate the problem at will, I expect it will be a waste of time returning this unit, especially as it would appear that Panasonic doesn't acknowledge these problems. I am not using HDMI leads and have a sky box and panasonic tv in the setup.
