Bump!
I have a similar issue, I have a large library and I left Media Monkey running overnight and woke up to have a long list of songs that had had DRM and wouldn't play of which i proceed to close (Oops!). I have no intention of searching through all my media to find them and was hoping there was some kind of scan/script or even a feature of MM that i have yet to discover.
Cheers in advance.
*** Sorry I didn't read your post properly stream recorder, I see the
Tunebite does find the files in directories.
Also In Windows 7 it is possible to add a column in the folder directory which indicates if a specific file has protection for anyone else that is looking for a solution.
