Hi. I'm Brian (from the Orchestrator videos). Thanks for watching. Glad to hear how excited you are about demoing Orchestrator!
Jörg is correct that some of the actions in the video come from a package that was created for the Orchestrator course (http://mylearn.vmware.com/mgrreg/courses.cfm?ui=www_edu&a=one&id_subject=38842). I am so accustomed to having those actions at my disposal that I didn't stop to realize that viewers like you don't have them. The error is mine.
As Jörg said in his reply to your post, we are working to make the package available. Thank you for your patience.
