plone with collective.flowplayer - video not appearing

I'm trying to setup some basic video sharing on my site using:

Plone 4.0.7 on Windows 7 collective.flowplayer 3.0rc4 test file: http://blip.tv/file/get/KimAronson-TwentySeconds1318.flv

The player does not show up when I view a single file (setting display to flowplayer does not help), just a message about making sure javascript/flash are enabled. This happens in both firefox and IE9; I don't think it's a browser settings or flash issue because I can see the player here just fine (in开发者_开发知识库 both browsers):

http://static.flowplayer.org/demos/plugins/javascript/playlist/horizontal.html

Any help appreciated! I'll paste my buildout deets if that helps:

eggs =
Plone
products.ploneboard
products.ploneformgen
products.carousel
collective.quickupload
collective.plonetruegallery[all]
collective.prettyphoto
