http://www.custombuildingproducts.com/ProductCatalog/SurfacePrep/Backerboards/OneQuarterInch_WonderBoardConcrete.aspx?user=diy&lang=en Scrolling down this page, you'll see links to a video showing how to lay down wonderboard. When I click on either low or high bandwidth, I get the video but no sound. Can anyone get sound? Know what I can do to hear it? My Windows mediaplayer works fine with other files but can't hear any of the videos on this site. Thanks Sam MP Version 9.00003354
