It means the VideoReader() call failed, such as might occur if 222.wmv was not found.

Wait, this sounds familiar now. There is a bug, I think it is in R2012b only, that affects structure access.
Edit line 91 to change
if( ~isempty(obj.NumberOfFrames) )
to
if( ~isempty(obj(1).NumberOfFrames) )
and likewise on other lines that encounter the same problem.
