sincerest apologies ukbobboy01, totally slipped my mind at the time, I have a sony dvd rw-U14A, in a custom made pc running windows xp pro, I used to be able to burn my films on it, others have had this problem apparantly, seems to be a software thing but at the present unsure, I will know more when I get a cd disc in and try the music burn, it says that this hardware is working in the properties, beyond that I am at a total loss, again sincerest apologies.
