[QUOTE=TomSinclair;5477]I streamed 864x480 @ 1000kbps and that part worked fine.

I embeded the YT player on a webpage and it could be viewed at 864x480 as the default, but the YT page used 640x360 as the default. /QUOTE]

FWIW, I've like to point out the 864x480 is not a resolution that YouTube (or really anywhere else) actually uses. 864x480 is actually 10 pixels too wide to be 16:9. I would set your video software and FMLE to be 854x480.
