Cant prepare DVD



When preparing a blank DVD R+ for recording the system gets to 21% and then ejects the disc saying invalid disc.
Any ideas what is wrong.


Which model and which discs (make and speed)?
For some reasons, Lite-on’s advice is to use “slow” discs - 4X or 8X. I have used HUNDREDS of 16X with no trouble… but then my drive has gone “faulty” (according to Lite-On). So one could argue that using “wrong” discs might have caused the fault.
