I started this thread in the wrong section: http://www.kriesi.at/support/topic/remove-read-more-button-on-portfolio-items and am moving it over to the right theme section.
I have been able to remove the "Read more" buttons from one of the portfolios: http://test.singularsoftware.com/video-tutorials-pluraleyes/, however, it isn't working for the other three:
http://test.singularsoftware.com/video-tutorials/
http://test.singularsoftware.com/video-tutorials-dualeyes/
http://test.singularsoftware.com/video-tutorials-presto/
Any ideas?
Create a new thread and tell me what problems you are encountering and what you want to know. 
There is no step 3 :)
