If you have the ATi Catalyst Control Center installed then you may have come accross hundreds if not thousands of event viewer records from “amdkmdag” with a single line of data “UVD Information”.
This is supposedly the graphics driver notifying you that a peice of video has not passed HDCP checks (read: DRM for video).
To disable this and suppress the messages, make the following registry change,
Windows Registry Editor Version 5.00
Or download and run this as a file to make the change.
