I found this in another thread and it worked perfectly for me in Linux Mint 16, Cinnamon.
I have Linuxmint 16 x64 installed. This worked for me.
Open a terminal to add this ppa and install HAL.
Type each line and press enter at the end of each line.
$ sudo add-apt-repository ppa:mjblenner/ppa-hal
$ sudo apt-get update
$ sudo apt-get install hal
When HAL is installed type each line of the following and press enter at end of each line.
rm -rf NativeCache AssetCache APSPrivateData2
When this is complete, go to the amazon prime web site and select a movie. This time the update will work and the movie will play correctly. You won't have to repeat this each time. Just do this once.
This completely fixed my issues with HBO as well as Amazon Instant Video.
Thanks to Vsenji333.
Also I added Pipelight:http://fds-team.de/cms/pipelight-installation.html

sudo pipelight-plugin --update
sudo pipelight-plugin --enable silverlight
# Type in 'Y' to accept the license of Silverlight and all required modules

I also added restricted Ubuntu extras from the Software Manager.
Hope this Helps.
