Issues with streaming flv in Captivate 4
I'm trying to view a streaming video in Captivate 4.
The video server is an in-house web server.
Nothing shows in Preview mode. When CP project is published, I get a dialogue box asking if I want to open or save:

If I open, Adobe Media Player opens. I don't want to view it in Adobe Media Player. I want the flv file to run in Captivate.
I have scoured the forums, but haven't seen an answer except maybe the Windows 2003 server issue (which I'm checking on.)
What am I missing?
