Dvd drive not recording

[Guest Niall]

Hi i am trying to burn music cd's from the windows media player.

It does every thing okay ans says the disc is finalized but when i try to

play it on the pc, it says "Blank Cd" and in a cd player it comes up with

"Not finalized".

Also when i try to copy documents to a cd it does the same, it copys them ok

but when i put the cd back in to check i get the message " Blank CD" again.

One more thing that may help i tryed a different make of disc and that

comes up with "windows does not support this cd-rw format " yet i have copyed

in it before in 2006!

All the updates are up to date

Please can some one help thank you Niall
