Hi Andrew -
I am a moderator for this forum and also helped Cornelius create The Agile PrepCast. I am also certified as a PMP, PMI-ACP, CSM, CSPO and CSP. I used The Agile PrepCast for 15 Category E - Independent Learning SEUs and submitted them for my CSP Certification on the Scrum Alliance web site. I am confident that you can still do this but I would also suggest that you verify this with the Scrum Alliance. I hope that helps and Happy Studying!
Kevin
