Hi Lauren,
Thanks for looking at this.
In the later browsers the @type attribute, where you give the MIME, 
along with comparing the served content type, is important.
The classid attribute says use a specific registered player for that 
MIME rather than choose the last installed/registered.
I have only seen classid used in <object> and only IE actuallly honors 
it now, but I think most late W3C browsers have stopped crashing when 
they find classid.

Give some html code and I will test on this end.
Does the file extension .x3d or .x3dv matter?

Right now HTML 5 folks are thinking about how to spec classid 

Thank You and Best Regards,
