Dynamic display block slideshow module for Drupal

I have tried to place my ddblock in a Node using

?php
$block = module_invoke('ddblock', 'block', 'view','1');
print $block['content'];
?

The block appears but it has the following html comment-like text around it. I have omitted the brackets (<>).

!-- dynamic display block slideshow --
!-- slider content --

and the following underneath

!-- slider-inner--
!-- slider--
!-- number pager --

!-- number pager --

!-- container-inner--

!--container--

!-- template --

What am I doing wrong?
