Errors in VIDEO STABILIZATION demo program

Hey,

I followed every step provided in "HELP" of MATLAB2011a for video stabilization synchronous scheduling demo model using DM642, but I do get following errors.

" Error reported by S-function 'dm642evm_video_dac' in 'videoworkflow_synctempl/Video Display subsystem/Video Display': Input signal matrix must not be larger than the display size."

"Error in port widths or dimensions. Output port 1 of 'videoworkflow_synctempl/Video Display subsystem/Y' is a [720x240] matrix."

Please help!
