Hi Richard -
I tried to do a test last night, and when I changed the setting to H.264, FMLE prompted me to change the file extension to f4v instead of flv, which I also did in the JWPlayer page that displays the video.
using live, not VOD.
Got a blank screen, even though video was being streamed.
As soon as I changed all the settings back to VP6/flv, the live video worked.
What am I doing wrong?
