DVD Disc not found

[Marcus]

I have a Sony Vaio GRT816S using XP Home SP2, with a pioneer combined DVD
RW/CD RW drive.

Everything has been working OK, now suddenly for no apparent reason any
inserted blank DVD is not recognised.
I am using JVC DVD-R discs and have, until now, successfully written several
video and data dvds.
The computer recognises and reads pre-recorded DVDs and reads and writes
CDs.

I have tried uninstalling and reinstalling the drive, using device manager
to no avail.

Sony's only suggestion so far is to wipe the computer and reinstall
everything from scratch - by the time I've managed that, the computer will
probably be obsolete.

Any help appreciated.
