I have some jQuery tabs one of which holds a flash video. When I play the video in one tab and click to another in FF or Safari the video stops along with the sound, clicki
We had the same issue. Flash video was embedded using swfobject.embedSWF(...), however, IE9 did not stop the video when the div was hidden using jquery.
Simple workardound: Call the swfobject.embedSWF(...) again to (re)load the swf into the same target div.
If you have a video with autoplay, try to load another empty swf file when hiding. Cheers
