You probably have not connected the scart cables correctly.
To view a recording from the DVDR you need to set your TV remote to AV1.
To record to the DVDR (for terrestrial channels) i.e. channels 1-5, you set it to the corresponding channel.
To record satellite channels, set the DVDR to A2, and then select the channel you wish to record.
Does your TV function OK with the DVDR off ?
