I have the latest all videos plugin on my website. I was trying the new Html5 format webm.  I tried embedding it with
{webm}Whateverthename{/webm}.  Is that the correct embed format. Or is there another. I'm puzzled. I have the plugin enabled. Apparently I'm getting and undefinedundefinedundefined at the end of the filename.

I have similar question, but nobody can help us!!! :-\
