Flash must be enabled for SpeedGrader to record video or audio feedback.  


Even if Flash was set to "Ask", it doesn't.  The trick: click on the "Secure" icon in the URL box and then select "Always allow on this site" for Flash.  You then need to reload the page and it all works fine!  (Thanks to Kevin Raskoff for getting this gem from Canvas tech support and passing it along for the rest of us.)
