My IE recently did the same thing. Can't watch imbedded video either ... I get the audio but the video box is blank. Must have been an update that caused the problem, but I have no idea which one because it auto-updates.
I resolved the issue by downloading Google Chrome as a browser. It works beautifully and I'm really liking it so far. Has lots of neat features.
Before I figured out it was Java, I was so disgusted I was considering a switch to Firefox (which I have used before) or Chrome. Thanks for the input on Chrome. BTW, when I ‘googled’ the error message and got answers, it did give the versions of Java that had the ‘bug’ that was causing my problem.
My nephew was in California playing tennis and the match was underway, my brother was frantically texting me to watch & couldn’t understand why I couldn’t get it .... I didn’t have time to download the latest Java. Thank goodness someone suggested the compatability view .... I pulled it up, typed in the web address for the livestreaming link and voila ... tennis! I saw the last couple of points of his doubles match, but it was better than seeing nothing. :-)
BTW, see this post on the Recipe Thread ... I think you will find it most interesting:
