FairUse4WM will extract the personally identifiable information (description keys) from Media Player for the purpose of allowing the user to improve the interoperability of legitimately acquired media files. At least one file with an active license is necessary. To actualize fair use rights with the new IBX, first run 'mirakagi' which will enter the IBX keys into the FairUse4WM blackbox-keys.txt text file. Next, you should use the attached version of FairUse4WM, 1.3Fix-2. This includes an important fix for a video corruption bug, often seen in scenes affording high compression.
