New Release - Firmware Version 3.03.13 for WD TV Live Hub (2/29/12)

The firmware update page states, “Blockbuster video download service will no longer be supported on the WD TV as of 3/31/2012. You will still be able to watch your purchased videos.” Is this referring to Blockbuster on Demand or is it something else? I’m curious because that’s probably the way we rent the majority of our movies. If anyone can elaborate that would be great. Thanks.
