I have a Panasonic freeview integrated television and also a Panasonic DVD recorder DMRE50. Taping analogue programmes is no problem but when trying to tape digital programmes, if the TV is switched off, on standby, or changed to another channel, the DVD only records the sound and not the picture but digital programmes can be taped if the TV is left on and on the same channel which is taping. Any help will be greatly appreciated. Thanks.
