Clearly, I'm just unlucky! baldtaco's suggestion means I've got to fork out again. Kate B's suggestion guided me to the Roxio website, from which it appears my version of the programme is as up-to-date as it can be. Now, SURVEY says they have no problems. When I try to copy a disc it says 'Disc copier could not detect any supported recorders. Please ensure your recorder is properly connected. If the problem persists, please re-install East CD & DVD Creator.' Not only have I installed deleted and re-installed the programme, everything else works perfectly well in my Philips DVD R/RW recorder.
Since you paid for Roxio and the AVG is free, my suggestion would be delete AVG and try the free AVAST. Are you absolutly certain that it these 2 programs that conflict because it seems rather odd to me. Two programs that do the same thing often conflict but its unusual for an anti virus to conflict with a burner. You could try one of the other free burners and see what that does or disable AVG when you're burning, or try AVAST.

Not so amigo. There's an excellent free version on that link I gave you, at the top right under Direct Download. I moved through several versions of that before eventually migrating to Prassi Ones, which I currently use. It did me an unfailingly great service. Simple, with a fair array of features for the average user, bloat free, and earns its corn.
