Rtmp video doesn't work on Captivate 7

Hello,

I'm trying to insert a rtmp video on Captivate 7, without any success.

I follow these steps:

1) Click on menu "Video > Insert Video";

2) Select the "Event video" tab;

3) Select "Already deployed to a web server, Adobe Media Streaming Service or Flash Media Server" and insert the URL rtmp://myDomain/vod/nomefile.flv or rtmp://myDomain/vod/nomefile (without .flv).

Captivate returns me this error message:

"Failed to load the video file. The file path or the URL may be invalid. Do you want to change the file path or the URL?"

If I choose "No", It appears the message "Video encountered an internal error" and then nothing happens.

If I choose "Yes" Captivate returns the message below

The video appears, but It doesn't work.

Any suggestions?

I'm using Red5 streaming server.

Thanks in advance.
