Most (if not all) of the How To videos located on this site were built on Googles WEBM html5 Video format.

If you are using Google Chrome you should have no problem with them playing in your web browser. Firefox seems to be able to play these videos as well with no issue. Microsofts IE web browser will not play these videos unless you have the proper codec installed. Here is a link to googles codec install package. https://tools.google.com/dlpage/webmmf
