DVD/CD media content not recognized

[Hapkido]

I have a client who is having a problem with her Toshiba Laptop DVD/CD
drive. The machine came with Vista Home Premium installed. It has all
updates, no spyware nor viruses, etc., when scanned with Malwarebytes and
Kaspersky AV 8.0.0.506.

When a burned or pressed disk is inserted into the drive, it spins up but no
content is recognized. Right-clicking on the drive in Computer and choosing
either "Open" or "Explore" results in the drive tray opening and a prompt
appears asking to insert a disk. When she inserts her camera's memory stick
into the reader, it prompts to format the stick but it fails. She can boot
the system with the Toshiba "Recovery Disk", so the drive does recognize
that particular media. Several different kinds of disks have been tried,
e.g., Office 2007, store-bought games, and home burned CDs, none of which
are recognized. Yes, these disks all work on another machine.

I had her uninstall the drive, reboot and let Windows reinstall it, which it
did successfully. She has followed the MSKB article to remove the "upper and
lower filters", which were not present. She has uninstalled the one burning
program that was installed, Ashampoo Burning Studio 8. Both "Chkdsk" and
"sfc /scannow" have been run... all without any change. She tried using
System Restore but all the Restore Points failed.

So, the drive does recognize at least one disk so it is doubtful the drive
itself is defective. But I have run out of ideas. Obviously, I am hoping
someone will recognize the problem and provide a fix. :~)

THANKS

Peter,

Thanks for responding. The MSKB article does not apply, however. What was
accomplished since I first posted was:

1. Run "sfc /scannow" again and this time it found errors but was only able
to fix some of them.
2. Disabled "ehtray.exe" from running at Startup
3. In "AutoPlay", changed all instances where Open or Play with Windows
Media Center appeared to something else, e.g., Windows Media Player.

These changes have resolved the problem. Why or how Windows Media Center got
involved in this is unknown to me. But at least now all types of media are
recognized, accessible and usable when inserted into the drive.
