Amazon instant video linux updating player
On some systems, users see a blank or black screen while attempting to play protected video content on services such as Amazon Instant Video.
The Adobe Flash Player automatically downloads a specific module used for protected video content playback on first use.
Occasionally, an incorrect or corrupted Adobe Access DRM (Digital Rights Management) module causes this problem.
You can see an error [3320 - Host Authenticate Failed] or a [2203 - IOError Event] if the video vendor displays error codes.
In order to make it visible and select "Go" from the Finder menu while pressing the "Option" key.
This will reveal the 'Library' directory/menu pick.
Now that the corrupted DRM module has been replaced, you can play protected content (this video is called the Getty "train" video).
Systems that downloaded the bad module cannot play protected video content until either 1) a Flash Player upgrade or 2) removal of the DRM module.
This document describes how to remove the DRM module manually on all supported platforms.
