I just updated to CS5 - I'm working on a custom video player. It works fine embedded in a web page both locally and on the network. It works fine in the debug player. However, when I test it in the authoring player I get a NetStream.Play.StreamNotFound error and no video. I have tried setting the Local Playback Security publish settings to both local and network - doesn't find the video either way.
It used to run fine in CS4 in the authoring environment.
Obviously it's hard to debug the problem when it doesn't fail in the debugger. ;-)
Am I missing a setting or ... ?
I just tested the issue with the included Flash video player component which does work fine in the authoring mode.
