I have a problem with the video module. I think that the requirements for the embed code are too high, because there are only a few sites from which I am able to add videos. For example, I wanted to add a video from the site archive.org
here's the code I wanted to add:
<iframe src="https://archive.org/embed/little_lord_fauntleroy" width="640" height="480" frameborder="0" webkitallowfullscreen="true" mozallowfullscreen="true" allowfullscreen></iframe>
'Ucoz' says that the code is not accepted because it doesn't include link to swf file. But there is nothing wrong with the code, it works just fine. Besides, now there are only a few sites that still include link to swf file in the embed code.
