Is there a difference between <br/> and <br />. In case you can't see the difference there's a space in the second. Any difference?
You need the space. When in doubt, use the validation service. http://www.w3schools.com/site/site_validate.asp

I think that it is compulsary for you to have a SPACE for XHTML. Cause in dreamweaver it always does <br />. So its always better using the sapce.
Yeah... I've always used <br /> I think it still works though... i just made a quick Notepad website with the <br/> tag and it worked.
