I purchased a Panasonic DMR-XW390 recorder. It records and plays back well.
When the recorder is recording a programme i can watch another programme of my choice.
If the recorder is recording two programmes simultaneously (as it is designed to do) I can watch only the channels that it is recording. I am unable to switch to another channel with any of the controls I have.
Any help, or leads to a knowledgable helper, will be appreciated.
