How do I watch EPIX on my PS3?
To get the EPIX app, go to the PlayStation Store on your PS3 and find EPIX in the Media/Apps Category. You can also find it available in the My Channels section under the TV/Video Services column on the XMB (Cross Media Bar).
1) Select the movie you want to watch by highlighting the movie image and pressing "X." Navigate down and activate the "Start Movie" button. The first time you do this, you will be prompted for a 6-digit code.
2) Go here (http://www.epix.com/devices/
) to get that code. Click on the PS3 icon, select your television provider from the drop-down and Sign In with your credentials.
3) Once you've successfully signed in, select the Devices tab on your Me page. Select PS3 and your 6-digit code will appear.
4) Enter your new 6-digit code on your PS3 and start watching movies. Please note: you must use your device code within one hour or you will need to get a new one.
