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,
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Atierecord
eRecordEnable = 0 (dword)
Or download and run the following file to make the change automatically.
