DRM . . . DRM . . . DRM . . . DRM ! ! ! There is no other acronym that brings up so much debate, and on both sides. There are all sorts of fancy capabilities of DRM (Digital Rights Manegement) and many different ways it can be used - but bottom line it is for one thing only - to Stop Piracy !!
Here are the basics and how to remove DRM. Many feel it is useless to try, since Microsoft seems to counter every new DRM crack with a new version of DRM. However that is a bit of a fallacy - you can still "UnDRM" many of the DRM protected files you download today using drmdbg.exe from 5 years ago. Many of the companies selling Audio and Video online simply do not want to upgrade their entire DRM system !!
DRM files come with a DRM header - the main two utilities that strip off the DRM headers also changed the filename. They add the following 8 characters to the beginning of the filename: [NoDRM]-
For example, if you download the DRM protected movie, "Too_Young_To_Die.wmv" and run it through either drmdbg or FairUse4WM - the file will be stripped of its DRM header, copied over to a new location, and renamed to "[NoDRM]-Too_Young_To_Die.wmv"
For WMplayer v9 I was able to get drmdbg to work . . . . briefly
Then I upgraded to WMplayer v10.00.00.3646 (typically referred to as WMplayer 3646), which is supposedly the best player version for UnDRM utilities. It did not fix the drmdbg problems but I was able to get FairUse4WM 1.3fix-2 to work !!!

Here is how you could download a rental movie, start it upo briefly just to pay the rental fee and get the license downloaded to your system, then UnDRM the rentalk so that it will play forever . . . regardless of the rental expirattion.
Download and extract to any folder, "FairUse4WM 1.23Fix-2" which consists of two files: mirakagi.exe and FairUse4Wm.exe. It is a bit hard to find because whenever it is hosted somewhere, it get taken down very quickly. The best bet is to check "eMule" - there are usually several copies of it there.
download a video file with DRM - typically this file will not yet have the corresponding license file
Delete and then rebuild (Individualize) your DRM files:
delete the folder: C:\Documents and Settings\All Users\DRM
individualize (rebuild) the DRM files by going to: http://services.wmdrm.windowsmedia.com/indivSite/en/indivit.asp and clicking "Upgrade".
run your downloaded video for a few seconds - just long enough to cause the license file to be downloaded
run the file mirakagi.exe to actualize fair use rights with the new IBX and click "Start"
this will enter the IBX keys into the FairUse4WM blackbox-keys.txt text file. The file is found here:
C:\Documents and Settings\"username"\My Documents\blackbox-keys.txt
Here is a sample of the contents of this file - a single line:
now start up FairUse4WM.exe (make sure it is version 1.3Fix-2 - which should be capable of interfacing with both Windows Vista and Zune software versions). This patched version includes an important fix for a video corruption bug, often seen in scenes affording high compression.
when finished, you will see a short Report - the one below is what you want to see:
This file will be FREE of DRM !!!
Test the file - and if OK, delete the DRM'd file
If problems occur, uninstall WMplayer 10, and reinstall the correct version (download v10.00.00.3646 Here)
