Many thanks Guy's!!! Just tried using some verbatim discs and it worked first time, and it's not as if they are vastly more expensive than the budget stuff that I've used for ages (in fact, if I take into consideration the budget ones wasted, then there is no difference!).
My only other query is why should the budget stuff work so well for so long (I'd never had a problem for over a year), and then all of a sudden they stop working completely? Any suggestions?
Still, once again, many thanks for your help, it is truely appreciated.
