Sony RDR-HX525 Recording issues

Greetings from Ireland
I am new to DVD recording and have just bought a Sony RDR-HX525 which is an amazing piece if equipment by the looks of it.
I think all is set up correctly (despite the confusuing manual) but i have a recording problem.
Whether I schedule a recording or just hit the Record button for instant recording, when it is finished it tells me “No title”.
The icon shows it is recording and it says it is saving OK - but time and again “No Title”
Any ideas where I go from here?
Thanks in advance
