It appears that you still need a license for the content to start with, that's kind of a big thing. I'm sure there will be more information about this later. The software has the file names of "DrmDbg.exe" and "DRM2WMV". DrmDbg.exe is supposed to get the KID and the Seed from memory when a DRM-enabled file is being decrypted/played. That spits out a .key file and DRM2WMV is supposed to take that .key and unprotect the WMV. This would leave you with a WMV file that is entirely unprotected and playable in anything that supports WMV playback."</i><br /><br />Oh-oh. :? This might be good news for those wanting to use DRM protected Windows Media Videos for personal use on other platforms where WM isn't present. But this is not good news for Microsoft and their clients. However the fun will not last forever: the DRM-remover might not be able to de-DRM WMV files forever as the structure of the WM DRM is such that it can be dynamically adjusted to this kind of "cracking". By the way, did someone else notice that DVD-Jon did not have anything to do with this DRM-cracking this time around... ;)
