CD/DVD Drive won't play DVDs but will play CDs!!!?

Posted under Registry Repair Software by admin

Ok this isn’t so much a question as just a compilation of all the info…
This can also be the case if DVDs play but not CDs… (in CD/DVD Drives)
But there a couple of things you can try…

A. Try fixing registry:
=== Backing Up Registry and Registry Key ===
CAUTION: The registry contains critical information and a
registry backup is essential. An incorrect registry
entry may cause serious system problems or prevent the
computer from starting. You will not be warned of any
incorrect registry entries. If the registry is not
backed up, the only way to recover the system is to
reinstall the operating system. Do not double-click the
Backup.reg file on the desktop unless you intend to undo
the changes you are making to the registry.

1. Click Start and type regedit in the text box.

2. Click "File" in the menu.

3. Click "Export" from the drop-down menu.

4. Click the down arrow beside "Save In" and select a Local Disk (i.e. C:)

5. Type Backup.reg in the File Name field.

6. Click Save.

=== Deleting UpperFilter and LowerFilter Registry Keys ===

1. Click Start and click Run.

2. In the Open box, type regedit and click OK.

3. Click the plus (+) sign beside HKEY_LOCAL_MACHINE.

4. Click the plus (+) sign beside System.

5. Click the plus (+) sign beside Current Control Set.

6. Click the plus (+) sign beside Control.

7. Click the plus (+) sign beside Class.

8. Locate the {4d36e965-e325-11ce-bfc1-08002be10318} key and click it.

9. On the File menu, click Export.

10. In the File name box, type savedkey and click Save. It is better to save the "savedkey" to the desktop.

11. Click the REG_MULTI_SZ data type UpperFilters (found in right window pane) and then click Delete on the Edit menu.

12. When you are prompted to confirm the deletion, click Yes.
NOTE: If this data type is missing, continue to the next
method.

13. Click the REG_MULTI_SZ data type LowerFilters (found in right window pane) and click Delete on the Edit menu.

14. When you are prompted to confirm the deletion, click Yes.

15. Quit the Registry Editor and restart the computer.

B. Unistall Driver
Note: CD/DVD drivers reinstall automaticlly upon reboot if missing.

1. Select Computer and click on Manage.

This will prompt you with a User Account Control Window.

2. Click on Continue.

This will open Device Manager.

3. Click the "+" sign next to CD/DVD Drive.

4. Click the first device listed under CD/DVD drive to highlight it.

5. Click uninstall to remove the CD/DVD device driver.

6. Click OK for confirmation.

C. If the above didn’t work (like in my case)
It is most likely not a software issue but a problem with the hardware. You can take it to back to where you got it and they will repair it or refund you if it is still under warranty. But you might be in the position I was stuck in where your warranty just expired. In that case find a cheap external hard drive capable of meeting your needs, a decent one will run you about 30-60 bucks.

Good luck, and I hope this helped!!!
