You will not be able to switch to another DVB-T channel
while a recording is in process. Indeed, the current
DVB-T tuner is dedicated on the current channel to

watched simultaneously. If you wish to watch another
channel while a recording is in progress, you are
therefore advised to switch to your satellite receiver or
any other reception device connected to your TV.
