Hi tv,
I'm not sure about the "From the web" tab you have mentioned, however I do think you should look at the codemirror module.
http://www.silverstripe.org/codemirror-module/
This plugin integrates CodeMirror into the HTML source editor of TinyMCE. This works around several problems with advcode such as the IFrame security pop-up in IE or the missing clean-up of text copied to clipboard by Word in certain browsers.
It will allow you to use Youtube and Vimeo embedded iframes in the HTML editor.
Regards,
