Film rentals and purchases are now available to Canadians via the Cineplex store site, some of them discounted, or even free, with Scene point redemption.
But to view this content you will need to install the Cineplex Media Manager, which is not available yet for Mac and Linux machines, and have Windows Media Player 11 installed.
The content downloaded from this web site is therefore limited to Windows machines (Windows XP SP2/newer, Vista or 7), Plays for Sure devices that can sync a 1500K video and the Xbox 360.
The site states they will be expanding their compatibility shortly.
