Did you try AS3 with CS4? There might be tighter security in AS3. Also check the code that does the load. You might need to set some security options in AS3

Just as I thought; it didn't make a difference. I need to figure out how the Flash CS4/AS2 demo is able to successfully get a snapshot and why the Flex/AS3 video player is not. --- In flexcoders@yahoogroups.com<mailto:flexcoders%40yahoogroups.com>, "jwebbsuccess" <jw...@...> wrote: > > I am testing the video player Flex app over 'file:///C:/<file:///C:\>' but the > Flash CS4 demo is technically on 'file:///C:/<file:///C:\>' as well.
