Hi, thanks for the reply. I have replaced my burner as it appears that it was the cause of my faulty burns. I have duely noted that you say TDK are not what they use to be so i will buy Verbatim next. I wish i could buy the other brand you speak highly of here in Australia but where i live the dont stock them and it will cost an arm and a leg to post them......Thanks again for all your help and this forum will be my first port of call in future when i need help......
