How do you enabling FMS 3.5 dynamic streaming/adaptive bitrate in Captivate?????

Hi all -

We are successfully using Captivate 4 to  create SWF files leveraging a Flash Streaming Media Server hosted on a  CDN.  YAY!

My question is, does anyone know how to  leverage the dynamic streaming / adaptive bitrate feature in FMS 3.5  with a Captivate file? I have spent an entire day searching all over Adobe forums and am surprised to see this is not documented ANYWHERE and given Captivate REQUIRES FMS to stream, it would be incredibly poor design if it cannot leverage the best feature FMS has to offer!

We publish to Flash Player 10,  and while FP 10 IS compatible with dynamic streaming, my challenge is  Captivate only allows one URI path and one stream name.

To  deliver dynamic streaming you have to have several files with different  encode rates availalbe.  But if Captivate only allows one stream name,  how do you point it to a stream that finds all the alternative files?

I've  explored this with 3 different CDNs and they don't know how to do it  (Limelight, CDNetworks and Internap).  I've called Adobe help and spent  over an hour to get no answer. I am now at my wits end!!!

The  reason I'm so interested is we are delivering a Moodle hosted eLearning  course to users around the globe with VERY different internet speeds.   We've followed all the best practices in encoding and this is the next  step in making our course accessble to ALL users.

For  those interested, our files are mostly less than 10 MB, though some are  as much as 50 MB, all encoded at 500 kbps.

THANKS!
