    Cannot play DVDs Getting Error Message

    I'm having a problem playing and recording DVD discs. I can pop a CD into my CD/DVD drive and Windows Media Player fires up and plays them fine. Whenever I insert a DVD I get this error message:


    I've tried using different players but still get the same error message. I found the following fix for this problem but it didn't work for me.

    1. Run Regedit
    2. Navigate the tree to HKEY_CLASSES_ROOT\DVD\shell\play\command
    3. Double click the (Default) value on the right side of the split dialog (Edit String dialog should appear)
    4. Copy the contents of the Value data field
    5. Click cancel on the Edit String dialog
    6. Right click on the right side of the split dialog
    7. Choose New->Expandable String Value
    8. Just hit enter if the cursor is allowing you to change the name of the new value
    9. Doublie click the New Value you just created (Edit String dialog should appear)
    10. Paste the string you previously copied into the Value Data field
    11. Click OK on the Edit String Dialog
    12. Now on the left hand side of the split dialog, highlight the folder HKEY_CLASSES_ROOT\DVD\shell\play\command
    13. Right click it, and choose Export
    14. Save this file to some location of your choosing, and some name of your choosing.
    15. Close regedit
    16. Go to the location you saved the file
    17. Right click the file, and choose the Edit option (should launch the file open in notepad (or some other text editor)
    18. You should see something similar to (Don't just copy and paste what I have below, because this PC has WinDVD installed):

    @="\"C:\\Program Files (x86)\\InterVideo\\WinDVD\\WinDVD.exe\" %1"
    "New Value #1"=hex(2):22,00,43,00,3a,00,5c,00,50,00,72,00,6f,00,67,00,72,00,61,\

    19. Now delete the first line:
    @="\"C:\\Program Files (x86)\\InterVideo\\WinDVD\\WinDVD.exe\" %1"

    20. Now replace everything in front of the = of the remaining line with just the @ character, final results should look similar to:

    21. Save the notepad file and close Notepad
    22. Now double click the file you just saved, a warning should appear saying you're going add stuff to the registry.
    23. Click Yes to Continue
    24. A Dialog should appear stating the values were added to the registry
    25. Re-open regedit
    26. Traverse back to HKEY_CLASSES_ROOT\DVD\shell\play\command (you should already be there)
    27. Now the value on the right hand side labeled (Default) should have the same Data as before, but the Type should indicate it is REG_EXPAND_SZ

    I just formatted this computer and I still have the problem. I don't know if this means anything but when I was in the registry, HKEY_CLASSES_ROOT\DVD\SHELL\PLAY\COMMAND I double clicked the DEFAULT line and copied the data value, "C:\Windows\system32\dischandler.exe" -%L I then pasted that line into the start search box and Windows Media Player started up. I just wanted to see if that path was valid and it seems like it was but still I have the error message when I put in a DVD. If anyone can help me with this, I would greatly appreciate it. Thanks.

    Re: Cannot play DVDs Getting Error Message

    Considering that you are having this problem on a fresh install it is quite possible that you have a bad drive-they don't last forever. Have you tried a dvd with data on it (such as your windows dvd)? Have you checked the permissions for that registry key? Take Ownership of file (see option 2 for an example on checking registry permissions). Before you start editing the registry you need to back it up. Export all of it to your desktop.

    Ordinarily, when a optical drive can read and write to a CD but not a DVD, and vice versa, the problem is fixed by either updating either the driver or firmware from the manufacturer's website.
