As I've said before, CD burning issues are a bit off topic
here.  Windows Media Devices are portable media players and
Windows Media Connect devices.  CD Burners are storage
devices like Flash drives and hard-disks.  Questions about
CD's and CD burning would probably get better answers in a
more storage-centered forum.  

So, now that I've established that I don't have a clue what
I'm talking about when it comes to CD burners, let's see
what I can find about the error code you're looking at. :)

Searching the web using 0xC00D11C9 I quickly found several
other forums where people have reported this error.  
However, I wasn't able to find any place where someone gave
informaion on how to get past this error.  So, that was a
dead-end.

Next I'll try researching the error in the SDK and Windows
source.  Looking in the SDK headers.  You've hit

NS_E_WMP_IMAPI_DEVICE_INVALIDTYPE

This is a Windows Media Player error code.  However, the
error didn't originate from there.  As the name would imply,
the error code is translated from

IMAPI_E_DEVICE_INVALIDTYPE

This is defined in the SDK header imapierror.h on line 17

Searching MSDN I find that IMAPI is the "Image Mastering
API".  Aparently, that is the application programming
interface for CD burning (cool!).  According to MSDN the
IMAPI_E_DEVICE_INVALIDTYPE error code results when:

"The recorder does not support an operation."

Doing a quick search for this error I found two places that
return it. Both of these are happen when a command is sent
to the CD drive and an unexpected or unknown status is
recieved back from the CD drive. (There are several
mechanisms that can be used to raise an error in Windows.  
My search shouldn't be considered exaustive.)

With my new-found knowledge I went back to the web to do a
search on IMAPI_E_DEVICE_INVALIDTYPE.  I did find a couple
of posts on various web-sites that talked about hitting this
error.  However, for these posts it appeared that the root
cause was a hardware failure in the CD drive.  This makes
sense.  In several reports of your problem the story stared
something like this: "It used to work, I didn't do anything,
and now it suddenly gives this error..."

So, after all that research here is my best guess (Remember,
I'm a portable device guy, not a storage guy.  You'll get
better more accurate advice if you ask a REAL expert).

The CD drive is giving an unrecognized response to the IMAPI
API.  Most commonly this can be caused by four diffrent
things.

1.  The CD Drive is in use
2.  The CD Drive needs to have the firmware or driver
updated
3.  The CD Drive is incompatible
4.  The CD Drive has failed

Now, before you go out and replace the CD drive, you should
check out my "troubleshooting CD burning post".  Perhaps
something there will get you working again.
