FLV for Flash Communication Server

[uxk8396]

Hi:
I have a book by Kevin Towes (Macromedia Flash Comm Server MX)
where he explains about using Flash MX to export FLV to be used for
Flash Communication server. I tried exporting my FLV using both
Flash MX and Flash MX 2004. I still cannot get it streamed thru the
FCS. I am sure the problem is not with my codings but with the flv,
most probably.
Any suggestion would be appreciated.

Thanks
H
