DRM in latest QuickTime cripples Adobe

The latest version of Apple's QuickTime media player has video production people venting their spleens after discovering that new digital rights management features have crippled the use editing software from Adobe.

Shortly after updating to QuickTime 7.4, legions of people charged chat groups to report they were unable to access files created with Premier and After Effects, two pricey Adobe programs used for editing video.

Those After Effects users unfortunate enough to have installed the update get a DRM-related error when trying to access their video files. It reads: "After Effects error: opening movie - you do not have permission to open this file (-54)."
