Twice recently, when trying to set BBC1 HD to record via the programme guide, the PVR locks up. The lockup occurs when the record button is pressed. The last time this happened I switched everything off and then restarted it, this unlocked the PVR but it locked up again when I tried to record BBC1HD again immediately afterwards. Re starting the PVR unlocked it again and I was able to record any other channel with no problem. Is this a peculiarity of BBC1HD or is it a problem with the PVR. I promise you that this is true, I was trying to record " The Frozen Planet" spooky or what!!!
