Quiz

There are a number of threads that seem similar but nothing on all four so I thought I'd ask again.....

It may be related to http://tracker.moodle.org/browse/MDL-6140, but I could get the videos to play, just not from the beginning (and I see the problem if I use an external URL)

I am trying to help someone embed a wmv file in a quiz (essay question).
Sometimes it works and sometimes it doesn't.
Often the controls disappear. Sometimes the display area disappears.
Sometimes you get an error message that the page does not exist, but the URL of the non-existent page is not the URL of the resource, but the URL of the resource with the file name replaced by "event.htm?1"
If I manually move the slide bar so that the video does not start from the beginning, it seems to work more often....

Works in IE, just not in FF... though IE tries to do a pop-up....
strangely enough, the audio will play sometimes in IE though there is no video (just the page not found error),

AND.... using IE it pops up a window with the error message, though the video and audio are playing in the initial page......

Same behavior using web page resource

Code used is based on a number of different variations of object and embed, including this:
<embed src="http://pathtofile/vid.wmv" showcontrols="1" showstatusbar="1" showdisplay="1" autostart="0" />
