Problem might be the .htaccess file
I didn't backup this one because it was hidden and overwrote it with:

DirectoryIndex index.html index.php
RewriteEngine On
RewriteRule ^surveillance-equipment/(.*)$ home.php [L]
RewriteRule ^surveillance-equipment/(.*)$ product.php [L]

Also, the manual of CDSEO points out some changes to product_details.tpl

FIND:

<tr>
{if $geid ne ''}<td width="15" class="TableSubHead">&nbsp;</td>{/if}
<td colspan="2"><br />{include file="main/subheader.tpl" title=$lng.lbl_details}</td>
</tr>


ADD BEFORE:

...


BUT there was already a code from altered cart before this.
So I don't know where to past the code: Before / after altered cart code?

Problem has been posted to Jon as well ...
