Using Embedded or webpage with weather forecast

I have tried show the next weather forecast with next two options. I am not using forecast IO for now.

Option 1 with stream/video local or webpage: http://selos.climatempo.com.br/selos/MostraSelo120.php?CODCIDADE=321,558&SKIN=padrao

Option 2 : embedded and editing the html to:
html with iframe:
iframe scrolling=“no” frameborder=“0” marginwidth=“0” marginheight=“0” style=“margin:0;padding:0;border:0;” width=“420” height=“315” src=“http://www.climatempo.com.br/tempo-no-seu-site/videos/selo/brasil/420x315

When I try a preview with CMS, the two options never work.
I can see only a black screen without content.

What am I doing wrong?

Never mind. The CMS preview is unable to show it, but the player works well.
