Here is an easy method to insert videos from YouTube, Metacafe, Google, etc. I have friends that have problems to place those videos, but with Viper’s Video Quicktags plugin allows you to easily insert videos, just simply click one of the new buttons that this plugin adds to the write screen (rich editor included) and then paste the URL that the video is located at into the prompt box, (great!). You can fully configure how the videos are displayed (width, height, alignment on the page) and much more. Best of all, it won’t break your page’s (X)HTML validation.
