Hi. Last night my pwt-420 decided it would stop recording. The red light flashes on the front as though recording is about to start but it remains flashing rather than turning solid because no recording starts. There is no problem with connection nor with signal strength. There is enough space on the HDD and I have not reached the 999 title limit. Under troubleshooting no other possible causes are listed - it simply says etc, which is of no use to anyone. The only option I can possibly see, and I don't know if it would work, is a reset to shipping condition. The problem with that is that whereas the manual tells me that I will lose tuning info, which is easy to restore, it doesn't tell me if I would lose recorded programmes and I have no external drive on which I could back things up. HELP!
