DVD player not recognized in Win 7

Hi all,
I have a client with a new Latitude E5440.  The DVD player is acting odd.  It will read data disks, movies/TV disks, and application disks for install.  What doesn't happen is burning or recognizing blank CD\DVD.  I replaced the driver with no luck, and Iset the UpnP in the services to automatic.  I can't think of much more that could be wrong.  Ideas?
Thanks,
Jim

Try checking the High and Low filters.

1. Close down all open programs
2. Open regedit.exe with Run as Administrator
3. Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\... .…{4D36E965-E325-11CE-BFC1-08002BE10318}
4. There should be one of, or both of, UpperFilters and LowerFilters
5. Click on UpperFilters, Edit Delete
6. Click on LowerFilters, Edit Delete
7. Close down regedit trees and close regedit
8. Open Device Manager and Uninstall DVD / CD Drive
9. Shut Down
10. Restart and DVD / CD Drive should come back with auto discover

See if this helps.

Agreed with John.  This is a fairly common issue.

Howdy.  In the key provided there was LowerFilters.  Deleted that, removed it from Device Manager, did the reboot and while it did reload the drivers for the CD, it still does not see the new/blank disks when inserted.
Thanks,

You could have a hardware problem. It is feasible it could read but not write or not recognize new media. Can you try a new DVD device?

Hi John,
The machine is new so I don't have a replacement.  May have to go the warranty route, but would rather as it's a new machine.  Clients get ticked off when that happens.
Thanks,
Jim

It is not uncommon for an early failure, so I think you might want to try the warranty route.

We did try with both types of blank media with out success.  It dos read and execute application software.

"Write" is a different function in the hardware DVD than "Read" and since this is a new computer, then it is likely faulty hardware.

Thank you all for the input.  The device is being replaced as none of the troubleshooting resolved the issue.
