I am trying to put a Flash Video into one of my slides but it is not working. I am using the .flv format and using the Slide Show with Jumps template. Any help would be nice!!!

This template doesn't support video at this time (though we intend on making it eventually support video).  It's an oversight of ours to permit authors to add them.  It does, however, support .swf files - so if you are able to convert your .flv to a .swf, it should work.
