Sony Vaio DVD drive will not read DVD's

Help please!
I have a Sony Vaio VGN-NR38S laptop on Windows 7. the DVD drive is an Optiarc Ad7560A. It will not recognise DVD, only CD's.

I don't know why this has happened but it will not play films and will not recognise the new version of Microsft Office I have just bought.

I am sure it seems to think it is a CD only drive.

I have tried uninstalling and reinstalling but to no effect. Checked for updates - nothing from Sony.
Any help much appreciated!

Sounds as if the DVD laser or electonics failed

You could try resetting Upper and lower filters but I don't hold out much hope

Run regedit and navigate to registry key

Highlight it and in the right pane, find the Upperfilters and Lowerfilters values.
Highlight each one in turn, right click and delete them.
Close regedit and restart the computer.
If in doubt make a restore point before making changes.
