videowall, data wall, multi display controller

[sidoffice]

Hi all just wanted to review this item as i have a question.. I purchased the iVw4 Standalone Videowall controller from http://www.iiview.com i have manage to output my playstation on four screens each at 19" as this unit can display in various modes clone mode, full mode or vertical replication.. it is awsome to play on such a big screen though planning to put 4x 42" screens together for a massive gaming experience.. what i wanted to know is there any way of overlaying a video footage over the existing game that i am playing on the videowall.. any help would be appreciated.
