If you wish to help and have a couple of minutes, browse to
the CF7 app, and look at the video (click photo of a girl named
Severn Suzuki, on the right side, second image down). Then do the
same with the CF8 app and see the error message:
Apparently, Flex cannot find the NetStream in the new server.
I have tried putting the FLV file on the same level as the main
HTML page; I have also tried using a complete absolute URL path to
the FLV. Always the same result.
What I find most curious about this is that it all works
fine in my 'localhost', which is now CF8 Developer Edition.
I don't think this is a CF issue, but I am posting this in
both the CF and the Flex forums, in hopes someone can come up with
something else to try.
