Which template are you using for your List&search type items?
And have you tried the template override for the default.php of the com_cck list view like I mentioned in my post?
Have you tried different variation for items? You can choose variation in tab "Template".
I copied the "simple" variation from SD Simple Simon template to the seb_one and seb_blog templates into variation folder. After that I can choose variation "simple" for my list item and even that ugly divs disappear.
what template are you using for List and for Item?
I have made a quick and dirty list template derived from seb_blog where I stripped out a lot of code. I use that as template for List and for the Item I use Seb Minima with simple variation from SD Simple. This way I got rid of all cck divs that I don't need.
Maybe you want to give my list template a try and see if it works for you.
